Sexy old school gay cruise bar in SoMa, it has a great atmosphere, with a very eclectic crowd. Everyone is friendly from patrons to staff. The music is very good and drinks are cheap. Powerblouse hosts the sexyiest gay parties in SF, with Thursday underwear night, but their event line up is actually changing all the time. So check on the internet before going. Weekend nights are a lot of fun and always packed with lots of hot guys around, in their best leather outfits. Powerblouse is a must stop for gays when visiting San Francisco.
I love this old school gay bar, it's fun, people are amazing (both bartenders and patrons) and the back room is great. I always pay a visit when I'm in San Francisco
