Hamburger Mary's is a restaurant chain originating from San Francisco, where the first location opened in 1972 as an open-air bar and grille in the SoMa neighborhood, founded by a group of hippies and gay men. The chain expanded in the late 1970s to locations in Portland, Honolulu, and Lahaina, with franchising managed by Jerry 'Trixie' Jones after an ownership split; it was incorporated as Hamburger Mary's International in 1997 by Stan Sax and Darren Woolsey, who standardized operations. Ownership changed again in 2007 to Ashley and Brandon Wright along with Dale Warner, leading to further expansion. The venues blend dining with entertainment, particularly drag performances such as 'Dining With The Divas,' Allusions shows, and Broadway Brunch, fostering an LGBT-friendly atmosphere known for its sassy, theatrical live events.
