Opinion
IKOLA, J.
The City of Garden Grove (city) enacted an ordinance (1) requiring “CyberCafes” to obtain a conditional use permit (CUP) to continue [430]*430in business, and (2) regulating their operations.1 Several CyberCafe owners (plaintiffs) sought a preliminary injunction, contending portions of the ordinance infringed free speech and privacy rights protected by the First Amendment of the United States Constitution and article I, sections 1 and 2 of the California Constitution. The court preliminarily enjoined the city from enforcing portions of the CyberCafe ordinance, and the city appeals. We conclude the court abused its discretion by preliminarily enjoining enforcement of the operational regulations, but appropriately exercised its discretion when it enjoined enforcement of the CUP requirement. Accordingly, we affirm the order in part and reverse it in part.
FACTS AND PROCEDURAL BACKGROUND
By memorandum of December 31, 2001, Joseph M. Polisar, the city’s chief of police, advised the city manager of the rapid growth in the number of CyberCafes operating in the city. In the space of two years, the number of these establishments had risen from three to a total of 20. Polisar’s memorandum detailed seven incidents of criminal activity occurring in or near four different CyberCafes during the last three months of 2001. Five of the seven incidents involved gang activity. The most recent incident, occurring the day before the memorandum was written, was the murder of a 20-year-old male while he was standing in front of a CyberCafe. Polisar also reported that patrol officers were finding schoolage children at these establishments during school hours, and he expressed concern about minors being able to access inappropriate and dangerous Web sites. Polisar concluded: “[T]he Police Department believes that it is vital that the City enact an ordinance regulating the use of ‘Cyber Cafe’s [Vc].’ ”
The city council responded quickly by enacting an emergency interim ordinance, which established a moratorium on any new CyberCafes and imposed certain operating restrictions on existing CyberCafes. By memorandum dated June 18, 2002, Polisar reported 10 additional incidents of criminal activity, which he associated with CyberCafes and which had occurred while the city was working on the draft of a new permanent ordinance. Also by this date Polisar reported 22 CyberCafes operating in the city, apparently an increase of two despite the enactment of the emergency moratorium. On July 9, 2002, the city council adopted ordinance No. 2573, its first attempt to [431]*431regulate CyberCafes with a permanent ordinance, with an effective date 30 days thereafter, August 8, 2002.
Before the effective date of ordinance No. 2573, the owners of five CyberCafes filed this action, seeking (1) damages pursuant to 42 United States Code section 1983 for the deprivation of rights, privileges and immunities secured by the federal and state Constitutions, (2) declaratory relief concerning the validity of the ordinance, and (3) a temporary restraining order, preliminary injunction and permanent injunction against enforcement of the ordinance. The court issued a temporary restraining order on August 7, 2002, and ordered the city to show cause, at a hearing scheduled for August 29, 2002, why a preliminary injunction should not issue restraining enforcement of the ordinance during the pendency of the action.
Although the record on appeal does not clearly indicate all of the subsequent proceedings, it appears no hearing was held on the request for preliminary injunction until January 30, 2003. By that time, three of the plaintiffs had dismissed their action as a result of a settlement, and the city had enacted ordinance No. 2591, substantially amending ordinance No. 2573. In connection with consideration of the new ordinance, Chief Polisar updated his report by memorandum dated November 20, 2002, this time reporting 23 CyberCafes in the city despite the moratorium, and “289 police activity calls since June 1, 2002.” Details of these “police activity calls” were not provided in the memorandum.2
Ordinance No. 2591 was passed by the city council on December 10, 2002. The hearing on the preliminary injunction began on January 30, 2003, but [432]*432before it was completed, the court called a recess to allow the parties to discuss settlement possibilities. Settlement was not achieved, and the hearing was eventually completed on February 27, 2003. The court took the matter under submission and, on March 21, 2003, issued its ruling “striking” portions of the CyberCafe ordinance (the ordinance).3
The ordinance required existing CyberCafes to apply for a CUP no later than July 31, 2003.4 The court enjoined enforcement of this provision, finding it to be “constitutionally impermissible,” because it “allows unfettered discretion in the issuance of permits . . . and does not withstand challenge as being narrowly tailored and operates as a prior restraint and is therefore] facially defective.”
Portions of the ordinance limited hours of operation and imposed a special curfew for minors during school hours unless accompanied by their parent or guardian. The court enjoined the provisions restricting access by minors during school hours. The court found restricting the “presence of minors during public school hours bears no basis to the declared legislative intent of public safety,” and requiring the presence of a parent or guardian during school hours “is overly burdensome . . . and not narrowly tailored.” The ordinance also imposed minimum requirements for the number of employees on the premises, and required the presence of licensed, uniformed security guards on Friday and Saturday evenings. The court enjoined these provisions finding insufficient “justification for accomplishing the legitimate governmental interest of public safety . . . and not sufficiently narrowed.”
Finally, the court enjoined a provision of the ordinance requiring CyberCafes to maintain a video surveillance system. It found this requirement imposed “an undue burden without adequate justification . . . and [was] not sufficiently narrow.”
DISCUSSION
Standard of Review
“We review an order granting a preliminary injunction under an abuse of discretion standard. [Citations.] Review is confined, in other words, to a [433]*433consideration whether the trial court abused its discretion in ‘ “evaluating] two interrelated factors when deciding whether or not to issue a preliminary injunction. The first is the likelihood that the plaintiff will prevail on the merits at trial. The second is the interim harm that the plaintiff is likely to sustain if the injunction were denied as compared to the harm the defendant is likely to suffer if the. preliminary injunction were issued.” ’ ” (People ex rel. Gallo v. Acuna (1997) 14 Cal.4th 1090, 1109 [60 Cal.Rptr.2d 277, 929 P.2d 596].)
But “[w]here the ‘likelihood of prevailing on the merits’ factor depends upon a question of law ... the standard of review is not abuse of discretion but whether the superior court correctly interpreted and applied [the] law, which we review de novo.” (Efstratis v. First Northern Bank (1997) 59 Cal.App.4th 667, 671-672 [69 Cal.Rptr.2d 445].) Constitutional issues are always reviewed de novo. (State of Ohio v. Barron (1997) 52 Cal.App.4th 62, 67 [60 Cal.Rptr.2d 342].) Here, the likelihood of prevailing on the merits does depend upon a question of law, because we are asked to conduct a facial review of the ordinance to determine whether it is constitutional. We conduct that review de novo. Of course, enjoining enforcement of a constitutional ordinance, or failing to enjoin enforcement of an unconstitutional ordinance, would also constitute an abuse of discretion within the usual formulation of the standard of review for the grant or denial of a preliminary injunction.5
1. Likelihood of Prevailing on the Merits
Plaintiffs challenge the ordinance primarily on First Amendment grounds. We have no doubt the ordinance implicates First Amendment activities. CyberCafes provide their customers with access to the Internet, allowing users to communicate privately by e-mail, acquire vast amounts of information from the World Wide Web, and even play interactive games. Commercial book publishers and distributors have long been entitled to First Amendment protection (Smith v. California (1959) 361 U.S. 147 [4 L.Ed.2d205, 80 S.Ct. 215]; Perrine v. Municipal Court (1971) 5 Cal.3d 656 [97 Cal.Rptr. 320, 488 [434]*434P.2d 648]), as have the proprietors of video arcades (People v. Glaze (1980) 27 Cal.3d 841 [166 Cal.Rptr. 859, 614 P.2d 291]), cabarets (Sundance Saloon, Inc. v. City of San Diego (1989) 213 Cal.App.3d 807 [261 Cal.Rptr. 841]), and movie theaters (Burton v. Municipal Court (1968) 68 Cal.2d 684 [68 Cal.Rptr. 721, 441 P.2d 281]). We perceive no rationale by which CyberCafes should be accorded less protection than any of these older or more traditional businesses. As the court below aptly observed, “The targeted business is a gateway to the information super highway[—]the modem new location for information’s dissemination.”6
The fact that First Amendment rights are affected, however, does not end the analysis. “That First Amendment rights are being utilized on the premises does not exempt a commercial entrepreneur from compliance with reasonable regulations under the police power.” (Burton v. Municipal Court, supra, 68 Cal.2d 684, 690.) “Expression, whether oral or written or symbolized by conduct, is subject to reasonable time, place, or manner restrictions . . . . [Restrictions of this kind are valid provided that they are justified without reference to the content of the regulated speech, that they are narrowly tailored to serve a significant governmental interest, and that they leave open ample alternative channels for communication of the information.” (Clark v. Community for Creative Non-Violence (1984) 468 U.S. 288, 293 [82 L.Ed.2d 221, 104 S.Ct. 3065].) “A regulation that serves purposes unrelated to the content of expression is deemed neutral, even if it has an incidental effect on some speakers or messages but not others.” (Ward v. Rock Against Racism (1989) 491 U.S. 781, 791 [105 L.Ed.2d 661, 109 S.Ct. 2746].) “[T]he requirement of narrow tailoring is satisfied ‘so long as the . . . regulation promotes a substantial government interest that would be achieved less effectively absent the regulation.’ ” (Id. at p. 799.) “[T]his standard does not mean that a time, place, or manner regulation may burden substantially more speech than is necessary to further the government’s legitimate interests.” (Ibid.) But provided “the means chosen are not substantially broader than necessary to achieve the government’s interest, ... the regulation will not be invalid simply because a court concludes that the government’s interest could be adequately served by some less-speech-restrictive alternative.” (Id. at p. 800.)
When, however, an ordinance or regulation requires permission of the government, such as a permit or license, before engaging in protected First Amendment activity, “ ‘ “precision of regulation must be the [435]*435touchstone” ’ [citation] and the standards set forth therein must be ‘susceptible of objective measurement.’ ” (Burton v. Municipal Court, supra, 68 Cal.2d 684, 691.) Ordinances governing the issuance of licenses fail to survive constitutional scrutiny where administrative officials are “granted excessive discretion in determining whether to grant or deny the license.” (Ibid.; see also City of Lakewood v. Plain Dealer Pub. Co. (1988) 486 U.S. 750, 757 [100 L.Ed.2d 771, 108 S.Ct. 2138] [“in the area of free expression a licensing statute placing unbridled discretion in the hands of a government official or agency constitutes a prior restraint and may result in censorship”].)
2. Balance of Hardships
An evaluation of the relative harm to the parties upon the granting or denial of a preliminary injunction requires consideration of: “(1) the inadequacy of any other remedy; (2) the degree of irreparable injury the denial of the injunction will cause; (3) the necessity to preserve the status quo; [and] (4) the degree of adverse effect on the public interest or interests of third parties the granting of the injunction will cause.” (Cohen v. Board of Supervisors (1985) 40 Cal.3d 277, 286, fn. 5 [219 Cal.Rptr. 467, 707 P.2d 840].) In this connection, another division of this court has held that regulation of business activities incidentally affecting the exercise of First Amendment rights does not automatically trigger a finding of irreparable harm. (Sundance Saloon, Inc. v. City of San Diego, supra, 213 Cal.App.3d 807, 814—818.) Irreparable harm from enforcement will not be recognized where the time, place and manner restrictions on First Amendment activities are narrowly drawn and adopted for legitimate governmental reasons, and where the restrictions are not otherwise constitutionally infirm. (Id. at p. 817.)
The Challenged Provisions of the Ordinance
We apply the above principles to determine whether the court abused its discretion when it impliedly found plaintiffs had established a likelihood of prevailing on the merits and the balance of hardships tipped in favor of plaintiffs.
1. The Conditional Use Permit Requirement Is Invalid Under the Existing Zoning Ordinance
Section 5 of ordinance No. 25737 requires existing CyberCafes to apply for a CUP no later than July 31, 2003, and waives the city’s usual processing fee for such a permit. Ordinance No. 2591 added chapter 8.82 to the Garden Grove Municipal Code. Chapter 8.82 established regulations for the operation [436]*436of CyberCafes, some of which are described, post. As relevant to the requirement of a CUP, however, section 8.82.030 of the new chapter 8.82 provides that conditions imposed by the CUP can override the general regulations established by Chapter 8.82. Specifically, the new section 8.82.030 states in part: “In the event that a use permit has been issued for a CyberCafe and the use permit conditions differ from the regulations established under Chapter 8.82 or are in addition thereto, then the use permit conditions shall govern and supercede over Chapter 8.82 regulations.” In short, the regulations established by chapter 8.82 do not bind the zoning administrator in determining the appropriate conditions to attach to the CUP. Thus, as plaintiffs correctly observe, “[t]he net effect of [section 8.82.030] is to change the regulations listed in [chapter 8.82] as suggestions to the zoning administrator which he or she can use or not use.”
To find the standards under which a CUP may be issued, one turns to section 9.24.030 of the Garden Grove Municipal Code, which governs land use actions and permits generally, including the issuance of a CUP. Section 9.24.030, subdivision (D)(4)(b), provides in part: “The hearing body shall approve an application for a conditional use permit when the information submitted by the applicant and/or presented at public hearing substantiates the following findings: [][]... [f] (ii.) That the requested use at the location proposed will not: [f] Adversely affect the health, peace, comfort or welfare of persons residing or working in the surrounding area, or [][] Unreasonably interfere with the use, enjoyment or valuation of property of other persons located in the vicinity of the site, or [f] Jeopardize, endanger or otherwise constitute a menace to public health, safety or general welfare; [][]... [f] The hearing body shall deny the application when the information submitted by the applicant and/or presented at the public hearing fails to substantiate such findings.”8
Plaintiffs established a likelihood of prevailing on the merits in their facial challenge to the CUP requirements of the ordinance. As our California Supreme Court long ago concluded: “A long line of decisions has held unconstitutional ordinances governing the issuance of licenses to conduct First Amendment activities where administrative officials were granted excessive discretion in determining whether to grant or deny the license.” (Burton v. Municipal Court, supra, 68 Cal.2d 684, 691.) In Burton, the court reviewed a municipal licensing ordinance that required motion picture operators to obtain a license from the Board of Police Commissioners. Inter alia, the ordinance allowed the board to “deny a permit if it finds that ‘the said operation will not comport with the peace, health, safety, convenience, good [437]*437morals, and general welfare of the public.’ ” (Id. at p. 687.) The Burton court invalidated this ordinance, finding “that it does not provide precise standards capable of objective measurement—the sensitive tools to be employed whenever First Amendment rights are involved.” (Id. at p. 692.)
In City of Lakewood v. Plain Dealer Pub. Co. (1988) 486 U.S. 750 [100 L.Ed.2d 771, 108 S.Ct. 2138], the high court explained why a facial challenge to a licensing statute that “vests unbridled discretion in a government official. . . whether to permit or deny expressive activity” (Id. at p. 755) is allowed without the necessity of first applying for and being denied a license. “First, the mere existence of the licensor’s unfettered discretion, coupled with the power of prior restraint, intimidates parties into censoring their own speech, even if the discretion and power are never actually abused.” (Id. at p. 757.) “Second, the absence of express standards makes it difficult to distinguish, ‘as applied,’ between a licensor’s legitimate denial of a permit and its illegitimate abuse of censorial power. Standards provide the guideposts that check the licensor and allow courts quickly and easily to determine whether the licensor is discriminating against disfavored speech.” (Id. at p. 758.)
Defendant argues the ordinance “does not pose a significant threat to either of the risks identified by the City of Lakewood Court.” The city makes the ipse dixit assertion “[t]here is simply no risk that an applicant for a CUP will somehow limit or otherwise censor the internet access of its patrons ... in order to make it more likely that they will be granted a CUP.” But the plain language of the ordinance does not support the city’s assertion. The ordinance governing the issuance of a CUP authorizes the zoning administrator, inter alia, to deny the application if the applicant fails to substantiate that issuance of the CUP will not “jeopardize [the] general welfare.” Surely this type of “unbridled discretion” to deny a CUP could well intimidate the applicant, for example, to propose software filters to limit full access to the Internet to better persuade the zoning administrator the proposed CyberCafe would not jeopardize the general welfare.
The city also asserts it “has no control whatsoever over the websites accessed by patrons of cyber cafes.” But it does. Under the ordinance, the zoning administrator has unfettered discretion in deciding what conditions to impose when issuing a CUP. The city does not identify how or in what manner that discretion is limited, and without objective standards, the zoning administrator retains the power to require software filters restricting access to any designated Web site.
Finally, the city argues it has given a narrowing construction to the CUP standards by granting a permit to owners “who have agreed to abide by the [438]*438time, place and manner regulations.” But the record contains no evidence to support this assertion. The city points to the settlement agreements with the plaintiffs who dismissed their actions, but these agreements are not a part of the record. Also, the conditions granted to three plaintiffs in settlement of litigation do not reasonably establish a “narrowing construction” of a facially unconstitutional permit requirement.
We conclude plaintiffs established a likelihood of prevailing on the merits with respect to the CUP requirement of the ordinance. “The [zoning administrator’s] ability to make decisions based on ambiguous criteria such as the ‘general welfare’ of the community effectively gives the [zoning administrator] the power to make decisions on any basis at all, including an impermissible basis, such as content-based regulation of speech.” (Dease v. City of Anaheim (C.D.Cal. 1993) 826 F.Supp. 336, 344.) We also conclude the interim harm to plaintiffs that would be caused by denial of the preliminary injunction outweighs the harm to defendant if the injunction is granted. Subjecting plaintiffs to a facially unconstitutional requirement as a condition to the continued operation of their business is a far more serious consequence to plaintiffs than is the consequence to defendant of not being able to impose a new CUP requirement on existing businesses. The court did not abuse its discretion in preliminarily enjoining enforcement of this portion of the ordinance.
2. Plaintiffs’ Facial Challenge to the CUP Requirement Is Not Time Barred
The city contends plaintiffs’ facial challenge to the CUP requirement is time barred by section 65009, subdivision (c)(1)(B) of the Government Code which requires any action “[t]o attack, review, set aside, void, or annul the decision of a legislative body to adopt or amend a zoning ordinance” be commenced and served on the legislative body within 90 days after the legislative body’s decision. The city argues it was not until January 15, 2003, when plaintiffs filed points and authorities in support of their application for preliminary injunction, that “[p]laintiffs raised for the first time the issue of whether the CUP requirement was valid,” and the complaint “was not amended to assert a constitutional challenge against the CUP requirement until February 25, 2003.” Observing that ordinance No. 2573 became effective on August 8, 2002, the city asserts the time to mount a facial challenge expired on November 6, 2002. We disagree. Plaintiffs are not time barred from challenging any portion of the ordinance.
In the original complaint, filed on July 30, 2002, nine days before the effective date of ordinance No. 2573, plaintiffs alleged “the face of the Ordinance [No. 2573], as well as its application, are unconstitutional, both [439]*439state and federal, for several reasons, including, but not limited to the fact that it is vague, ambiguous and overbroad on its face, that it is being applied unequally, that in its application it restricts the right of free speech and assembly designed to communicate and disseminate ideas and information.” In seeking declaratory relief, plaintiffs alleged, “the Ordinance [No. 2573] is invalid and unenforceable, both on its face and as construed and applied by Defendants.” Plaintiffs prayed for “an order imposing a temporary restraining order, a preliminary injunction and a permanent injunction against Defendants . . . enforcing the Ordinance [No. 2573] in any manner,” and for a declaration “that the Ordinance [No. 2573] is unconstitutional, invalid and void on its face and or as applied to Plaintiffs.”
Thus, the original complaint did not limit plaintiffs’ challenge to specified parts of the ordinance. The entire ordinance was challenged when the complaint was filed. Under these allegations, plaintiffs are not required to seek relief from every part of the ordinance by way of preliminary injunction on pain of being time barred as to other parts when the case is tried on the merits. Plaintiffs may choose those parts of the ordinance most likely to qualify for preliminary relief and reserve their challenge on other parts to the time of trial on the merits. Similarly, plaintiffs may surely expand or contract the preliminary relief they seek, so long as that relief is encompassed within the allegations made in the complaint. The city cites no authority that would forever limit plaintiffs to the arguments made in their first memorandum of points and authorities filed with their application for a temporary restraining order. The contention that plaintiffs are time barred from contesting the CUP requirement is without merit.
3. The Daytime Curfew for Minors is Valid
Ordinance No. 2591 added section 8.82.020, subdivisions (1) and (2) to the Garden Grove Municipal Code, which establish restrictions on the hours of operation and the hours during which minors are permitted on the premises of a CyberCafe. With respect to the hours for minors, section 8.82.020, subdivision (1) provides: “Minors may not enter or remain in a CyberCafe establishment on any day after 10 p.m.; or between the hours of 8 a.m. and 3 p.m. during those weekdays when the public school system within the City jurisdiction is open and classes are being conducted. ['}[]... [][] This time restriction shall not apply when a minor is accompanied by a parent or guardian (with the guardian being able to authenticate guardianship).” With respect to overall hours of operation, section 8.82.020, subdivision (2) provides: “The hours of operation shall be limited to 7 a.m. to 1 a.m., daily; excepting Friday and Saturday nights wherein hours of operation shall be limited to 7 a.m. to 2 a.m.”
[440]*440The court enjoined only that part of section 8.82.020 that prohibits minors from entering or remaining in a CyberCafe during school hours on schooldays (the daytime curfew), and this is the only portion of the curfew provisions argued on this appeal. Accordingly, we limit our review to the daytime curfew.
Because the daytime curfew restricts the ability of minors to communicate on the Internet at CyberCafe locations during seven consecutive hours each school day, we review this regulation to determine whether it is a reasonable time, place, and manner restriction on First Amendment activities. As noted, ante, a reasonable time, place, and manner restriction on First Amendment activities is constitutionally permissible if it is content neutral, is narrowly tailored to serve a significant governmental interest, and ample alternative channels for communication remain open. (See Clark v. Community for Creative Non-Violence, supra, 468 U.S. 288, 293.) The court found the restriction to be content neutral, and we agree. Plaintiffs confine their argument to the second prong, i.e., they assert the restriction on daytime access by minors is not narrowly tailored to serve a significant governmental interest.
The city urges public safety generally, and concern for the safety and well being of minors specifically, as the significant governmental interests served by the ordinance.9 Ordinance No. 2573 recites earlier findings made by the city council in connection with the interim urgency ordinance that “a significant number of crime and gang related activities were occurring in and about certain businesses commonly known as ‘CyberCafes,’ ” and that “reasonable time, place, and manner regulations” were “necessitated]” because “CyberCafes have been continuously and systematically visited by gang members.” The city council made additional findings when it adopted Ordinance No. 2591, including: “A significant number of patrons [at CyberCafes] are minors”; “A consistent pattern of violence has occurred in and about CyberCafe locations”; “Gang activity has been documented by the Police Department at a number of these businesses”; “In two separate incidents (12/30/01 & 6/08/02), two minors were murdered in connection with CyberCafe operations”; “Numerous physical assaults have occurred at CyberCafe locations . . . and two other cases of shootings have been documented”; and “The enactment of time, place, and manner restrictions as provided herein will provide measures to reduce the potential for crime activity at these locations.”
[441]*441We recognize “courts should not too readily discount the stated need for and justifications expressed by legislative bodies in support of laws even when those laws incidentally affect First Amendment rights.” (Sundance Saloon, Inc. v. City of San Diego, supra, 213 Cal.App.3d 807, 821.) Still, we are cautioned “the ordinary deference a court owes to any legislative action vanishes when constitutionally protected rights are threatened. ‘The rational connection between the remedy provided and the evil to be curbed, which in other contexts might support legislation against attack on due process grounds, will not suffice.’ ” (Spiritual Psychic Science Church v. City of Azusa (1985) 39 Cal.3d 501, 514 [217 Cal.Rptr. 225, 703 P.2d 1119].)
Without question, the city has a substantial interest in public safety, and in the safety and well being of minors specifically. (See Sable Communications of California, Inc. v. F.C.C. (1989) 492 U.S. 115, 126 [106 L.Ed.2d 93, 109 S.Ct. 2829].) Thus, the issue we decide is whether the daytime curfew is narrowly tailored to advance that interest. We conclude the daytime curfew passes constitutional muster as a narrowly tailored restriction that advances the city’s interest in the safety and well-being of minors.
Chief Polisar’s memorandum of November 20, 2002, which was provided to the city council in connection with its consideration of ordinance No. 2591, reported CyberCafes “attract gang members and juveniles as patrons,” and had generated “289 police activity calls since June 1, 2002.” The memorandum also told the city council: “The Cyber Cafes have become a business type of choice for non-territorial gang members to congregate. The chosen establishments become an informal gang turf for the members of the gang and by using formal and informal methods of communication, these establishments quickly become known in the gang community as gang hangouts. Gang members know which businesses have been chosen by rival gang members to frequent. Unfortunately, the presence of gang members in an environment where minors are present can have unsettling effects. Minors can be recruited into the gangs, may be exposed as witnesses to gang violence, or most severely, may become innocent victims of gang violence. The police department has several documented crimes where gang members have shot weapons from the outside of Cyber Cafes into the business. . . . Since the non-territorial gang members have chosen to use Cyber Cafes as their chosen business to frequent, the potential for gang violence is increased at these establishments.” (Italics added.)
From the information provided, the city concluded that excluding minors from CyberCafes during school hours would advance its significant public interest in their protection and safety. That conclusion is reasonable. Although parents presumably believe their minor children are in school while it is in session, they are not in a position to assert direct supervision and control [442]*442during school hours. As noted by the chief of police, if CyberCafes allow minor children on the premises during school hours, the potential that gang members will recruit minors is increased, as well as the potential that minors will become witnesses or victims of gang violence. Thus, the “regulation promotes a substantial government interest that would be achieved less effectively absent the regulation.” (Ward v. Rock Against Racism, supra, 491 U.S. 781, 799.) This is all that is required to meet the “narrow tailoring” requirement. {Ibid.)
Further, the means chosen to advance the city’s interest are not substantially broader than necessary. The city perceived that danger to minors existed in the risky environment of the CyberCafes. The daytime curfew is limited to CyberCafes with their risky environment, and to those times when the students are not under the presumed direct control and supervision of their parents. An exception is made where the parent or guardian is present to provide that supervision. Even if we could conceive a less speech-restrictive alternative to achieve the city’s interest, the daytime curfew would not be invalidated. “Narrow tailoring” does not require the city to select the least restrictive alternative. (Ward v. Rock Against Racism, supra, 491 U.S. 781, 799-800.)
Finally, plaintiffs presented no evidence to establish the lack of “open ample alternative channels for communication.” (Clark v. Community for Creative Non-violence, supra, 468 U.S. 288, 293.) It is common knowledge that alternative channels for communication over the Internet are abundant. Many have Internet access at home. Schools (where the minors should be in any event) commonly provide Internet access, as do public libraries. And, of course, the CyberCafes themselves are open to minors, even without parental supervision, for seven hours each day.
In finding the daytime curfew constitutionally invalid, the court appeared to reweigh the evidence to determine whether the need for regulation was supported factually. The court stated it found “the restriction on the presence of minors during public school hours bears no basis to the declared legislative intent of public safety. ... No ‘cyber cafe’ crimes have been reported to the police during school hours.” In doing so, the court engaged in impermissible legislative factfinding. “ ‘It is not the judiciary’s function ... to reweigh the “legislative facts” underlying a legislative enactment.’ [Citation.] The scope of judicial review must be cognizant that the factual determinations necessary to the performance of the legislative function are of a peculiarly legislative character.” (Alfaro v. Terhune (2002) 98 Cal.App.4th 492, 510-511 [120 Cal.Rptr.2d 197].) “ ‘[T]he courts will not . . . engage in a trial at which the court, as trier of fact, determines the factual basis upon which the Legislature may act.’ [Citation.] ‘In other words, in enacting legislation the Legislature [443]*443has already, in the exercise of the legislative power, determined the facts necessary to support the legislation. The courts cannot revisit the issue as a question of fact, but must defer to the Legislature’s determination unless it is palpably arbitrary. . . . Consequently, we must uphold the challenged legislation so long as the Legislature could rationally have determined a set of facts that support it.’ ” {Id. at p. 511.) Here, the city council could rationally have determined from the facts before it that the daytime curfew was a needed prophylactic measure to deter minors from being recruited or victimized by gangs when they should, under law, be in school. So long as the daytime curfew passes scrutiny under the First Amendment, it is not for the courts to reweigh the facts considered by the city council when it determined the ordinance was needed.10
Accordingly, on the evidence presented to the court, the daytime curfew passes constitutional muster. The plaintiffs failed to demonstrate a likelihood of prevailing on the merits. We conclude the daytime curfew is a content-neutral, narrowly tailored restriction that advances a significant governmental interest, leaving open ample alternative means of communication, and that the restriction does not restrict more speech than is necessary to advance the city’s legitimate interest. The court abused its discretion when it preliminarily enjoined enforcement of the daytime curfew.
[444]*4444. The Employee and Security Guard Requirements
Ordinance No. 2591 added section 8.82.020, subdivision (3) to the Garden Grove Municipal Code, which established staffing requirements for a CyberCafe. Subdivision (3)(a) requires a CyberCafe to have “a minimum of one employee over the age of 18 on the premises during all hours of operation.” For those CyberCafes having more than 30 computers on the premises, subdivision 3(a) requires an additional employee over the age of 18 years, except during the school hours of 8:00 a.m. to 3:00 p.m. Subdivision (3)(b) also requires the presence of a licensed uniformed security guard on the premises on Friday and Saturday nights between 8:00 p.m. to 2:00 a.m. The security guard can be counted as the additional employee for CyberCafes having more than 30 computers, but the owner of the establishment is prohibited from acting as the required security guard.
The impact on First Amendment activities of these staffing and security guard requirements is tenuous at best. Some would say there is no impact at all. But the ordinance does somewhat restrict the manner in which First Amendment activities may be conducted. Thus, communication over the Internet in a CyberCafe is prohibited unless conducted on premises having the required number of employees and, during specified hours, a security guard. We review these requirements to determine whether they are content-neutral, narrowly tailored manner restrictions, which leave open alternative channels for communications.
As found by the trial court, the staffing requirements make no reference to the content of any communication and are thus content neutral. And, as with the daytime curfew, ample alternative channels for communication are available. The remaining question is whether the staffing requirements are narrowly tailored to advance the city’s substantial interest in public safety.
Chief Polisar’s report to the City Council pointed to the potential for gang violence at CyberCafes because nonterritorial gangs had chosen these locations as the “business type of choice” at which to congregate. It cannot seriously be suggested that the presence of a responsible adult on the premises does not promote the city’s interest in public safety and deterring gang violence. It does. Absent this regulation, CyberCafe owners would be free to staff their businesses with minors, an option most would agree is a less effective means of advancing the city’s interest in public safety.
The city also concluded that the presence of two adults at CyberCafes having more than 30 computers is reasonably necessary for effective supervision, and that the presence of security guards during limited hours on Friday and Saturday nights would advance its interest in public safety. Thus, staffing [445]*445requirements are increased where the potential exists for a greater number of customers and during hours expected to have the greatest demand for the services of the CyberCafe. Absent the requirements of an extra employee at larger establishments and a security guard during high volume hours, the city’s interest in public safety and deterring gang violence would be less effectively served. Further, the staffing requirements are not substantially broader than necessary. The city is not required to select the least restrictive alternative means for advancing its legitimate interest. (Ward v. Rock Against Racism, supra, 491 U.S. 781, 799-800.) “Where ordinances are concerned, it is not the business of the court to write the statute.” (City of San Jose v. Superior Court (1995) 32 Cal.App.4th 330, 338 [38 Cal.Rptr.2d 205].)
Given the well-demonstrated criminal activity observed at CyberCafes, and their tendency to attract gang members, the court should not have second-guessed the city council’s judgment and discretion. The staffing requirements are content neutral and are narrowly tailored to serve a significant governmental interest. Ample alternative means of communication remain open, and the requirements are not substantially broader than necessary. Accordingly, the court abused its discretion by enjoining enforcement of the employee and security guard requirements.
5. The Video Surveillance Requirement
The final challenged provision of ordinance No. 2591 is the addition of section 8.82.020, subdivision (8) to the Garden Grove Municipal Code, which requires CyberCafes to install a video surveillance system. The video system must be “capable of delineating on playback ... the activity and physical features of persons or areas within the premises,” and must “cover all entrances and exit points and all interior spaces, excepting bathroom and private office areas.” “The system shall be subject to inspection by the City during business hours” and “[t]he videotape shall be maintained for a minimum period of 72 hours.”
First, we note what the appeal on this issue is not about. Plaintiffs argue, “Garden Grove has decided that the plaintiffs must collect video records of all its patrons and make those images available to the government for any purpose whatsoever.” But reasonably interpreted, that is not what the ordinance requires. “The system shall be subject to inspection” and the “videotape shall be maintained for a minimum period of 72 hours.” The ordinance does not require the owner to allow inspection of the tape upon demand. For enforcement purposes, the city can assure itself the video surveillance system is operational. That is all the ordinance requires.
At the hearing on the preliminary injunction, counsel for the city agreed with this interpretation, and acknowledged the city could not take possession [446]*446of the video tape without legal process such as a search warrant. Upon hearing this reasonable interpretation of the ordinance by counsel for the city, plaintiffs’ counsel said, “[I]f that’s the city’s understanding . . . then that issue can be resolved.” The court reiterated the interpretation, and inquired whether the stipulation to that interpretation would suffice. Plaintiffs’ counsel stated, “Yes, if that’s the stipulation, that’s fine. I can handle that. If that’s what the city is saying, that we are not required, absent legal process, to turn a tape over to the city under the terms of this ordinance.” Counsel for the city stipulated to this interpretation on the record, and the court did not further address the issue. The issue having been withdrawn from consideration by the trial court, it did not form any part of the basis for issuance of the injunction.
Plaintiffs offer no argument why the commonsense interpretation acknowledged before the court below should now be ignored, and an unreasonable interpretation substituted as a strawman in support of the injunction. While the normal rule of appellate practice requires an order to be affirmed if it is correct on any ground, (Schubert v. Reynolds (2002) 95 Cal.App.4th 100, 110 [115 Cal.Rptr.2d 285]), we cannot affirm an order based on an erroneous interpretation of the ordinance before us. Upon our de novo review of the video surveillance portion of the ordinance (People ex rel. Lockyer v. Shamrock Foods Co. (2000) 24 Cal.4th 415, 432 [101 Cal.Rptr.2d 200, 11 P.3d 956]), relying on its plain meaning (Roberts v. City of Palmdale (1993) 5 Cal.4th 363, 376 [20 Cal.Rptr.2d 330, 853 P.2d 496] [“The Legislature’s intent is best deciphered by giving words their plain meanings”]), and remembering that even where two interpretations are possible the court will choose that interpretation rendering the ordinance constitutional (Shealor v. City of Lodi (1944) 23 Cal.2d 647, 653 [145 P.2d 574]), we conclude the interpretation acknowledged by all parties in the court below is correct. While the ordinance permits the city to inspect the video system to ensure it is operational, the ordinance does not subject the videotape to inspection by the city on demand.
Turning to what the video surveillance portion of the ordinance does say, we are not persuaded the video surveillance system affects First Amendment activity any more than does the presence of an adult employee and/or security guard.11 The ordinance does not require video surveillance of e-mail or images from the Internet appearing on the customer’s computer screens. The [447]*447ordinance requires only that the system be capable of showing “the activity and physical features of persons or areas within the premises.”12 This is no more than can be observed by employees, security guards, or indeed, other customers. That the video system has a 72-hour memory that may be better than the short-term memory of the average security guard, customer, or employee is not a distinction of constitutional significance on First Amendment grounds. For the reasons discussed, ante, in connection with the employee and security guard requirements, the video surveillance requirement is a content-neutral manner restriction, narrowly tailored to advance the city’s legitimate interest in public safety and deterrence of gang violence. Perhaps for this reason plaintiffs turn to article I, section 1 of the California Constitution, and assert that video surveillance invades the privacy of their customers.
“[A] plaintiff alleging an invasion of privacy in violation of the state constitutional right to privacy must establish each of the following: (1) a legally protected privacy interest; (2) a reasonable expectation of privacy in the circumstances; and (3) conduct by defendant constituting a serious invasion of privacy, [f] Whether a legally recognized privacy interest is present in a given case is a question of law to be decided by the court. [Citations.] Whether plaintiff has a reasonable expectation of privacy in the circumstances and whether defendant’s conduct constitutes a serious invasion of privacy are mixed questions of law and fact. If the undisputed material facts show no reasonable expectation of privacy or an insubstantial impact on privacy interests, the question of invasion may be adjudicated as a matter of law.” (Hill v. National Collegiate Athletic Assn. (1994) 7 Cal.4th 1, 39—40 [26 Cal.Rptr.2d 834, 865 P.2d 633].)
Plaintiffs do not explain why persons in a public retail establishment have a protected privacy interest in either their activity on the premises or their physical features, why any reasonable expectation of privacy would attach in such circumstances, why the asserted invasion can be considered serious, and why, in any event, if the privacy interest both exists and is invaded, the governmental interest sought to be advanced does not make the minimal intrusion constitutionally permissible.13 Instead, plaintiffs make only general [448]*448references to cases involving the right of privacy. A brief must contain reasoned argument and legal authority to support its contentions, or the court may treat the argument as waived. (People v. Stanley (1995) 10 Cal.4th 764, 793 [42 Cal.Rptr.2d 543, 897 P.2d 481].)
Even if the argument were not waived, we do not find any legally protected privacy right of the customers in their activity on the premises or their physical features. Hill v. National Collegiate Athletic Assn., supra, 7 Cal.4th 1, 35, identified two classes of legally recognized privacy interests: “(1) interests in precluding the .dissemination or misuse of sensitive and confidential information (‘informational privacy’); and (2) interests in mating intimate personal decisions or conducting personal activities without observation, intrusion, or interference (‘autonomy privacy’).” The video surveillance system required by the ordinance does not intrude on either type of interest. A person’s physical features are not “confidential,” nor are activities on the premises of a public retail establishment. No legally recognized informational privacy right can attach to either. Nor can it reasonably be understood that the observation of persons using a computer in a CyberCafe involves intrusion either on the mating of an intimate personal decision or on the conduct of a personal activity.14 Plaintiffs do not explain why observation by a video camera intrudes on privacy any more than observation by employees or other patrons.
Finally, even if observation by a video surveillance system in these circumstances did somehow intrude on a legally recognized privacy right, a reasonable expectation of privacy is wholly lacking. “A ‘reasonable’ expectation of privacy is an objective entitlement founded on broadly based and widely accepted community norms.” (Hill v. National Collegiate Athletic [449]*449Assn., supra, 7 Cal.4th 1, 37.) With the near ubiquitous use of video surveillance in retail establishments, at automated bank teller machines, and at road intersections, it is difficult to imagine, certainly at the preliminary injunction stage, that the customer’s expectation of privacy is reasonable under the circumstances. Further, no evidence was presented in the trial court in support of the privacy claim. Nor could such evidence easily be presented. Each of the declarations submitted by CyberCafe owners in support of the temporary restraining order and preliminary injunction disclosed they already had installed video surveillance systems on their own. Although the issue of whether a legally recognized privacy interest is present is a question of law, the issues of whether a reasonable expectation of privacy is present and whether the conduct in question is a serious invasion of privacy are mixed questions of law and fact. (Id. at p. 40.) Without any evidence on these questions, plaintiffs could not establish a likelihood of success on the merits, either on First Amendment or on privacy grounds, and the preliminary injunction should have been denied. Accordingly, the court abused its discretion when it preliminarily enjoined the video surveillance requirements of the ordinance.15
[450]*450DISPOSITION
The court’s order preliminarily enjoining the enforcement of the CUP requirement contained in section 5 of Ordinance 2573 is affirmed. The court’s order preliminarily enjoining the enforcement of: (1) that portion of section 8.82.020, subdivision (1) of the Garden Grove Municipal Code, restricting access by minors between 8:00 a.m. and 3:00 p.m.; (2) section 8.82.020, subdivision (3) of the Garden Grove Municipal Code, regulating the number of employees and requiring security guards during certain hours; and (3) section 8.82.020, subdivision (8) of the Garden Grove Municipal Code, requiring video surveillance systems, are reversed. In the interests of justice, the parties shall bear their own costs on appeal.
