The Alcazar Theater sits at the scruffy western fringe of San Francisco's Union Square theater district. As a rental theater, it irregularly hosts revues, cabaret, comedians, and other theatrical events of varying quality.

San Francisco architect and Shriner, T Patterson Ross, was responsible for this Islamic fever dream of a building. He also designed lavish, but less crazed, homes for the wealthy residents of Russian Hill, Presidio Heights and Palo Alto.
