This classic theater, designed by architects James and Merritt Reid (who also did the Fairmont Hotel and the original Cliff House), has been a San Francisco favorite since it opened in 1926. Transformed into a twin-screen venue in 1978, the Balboa is the quintessential second-run theater, offering an eclectic mix of Hollywood studio movies, independents, documentaries, and foreign films. Judging from the kudos it receives from adoring moviegoers who subscribe to its newsletter and post to its Web site, the Balboa is clearly among the Richmond District's more beloved entertainment venues. And it's a bargain: General admission is $8.50, matinees are $6, and admission is always $6 for seniors, children, and students and faculty members with IDs on "School Night," every Thursday. On your birthday you get in free.
