Polk Street has all but been annexed to the Marina, but once upon a time, there was a hustler-filled gayborhood called Polk Gulch - of which the Cinch is the sole survivor. Still, the relaxed, amiable dive and its unshakeable 1970s vibe continue to flourish on Polk as it has for decades. Known for going all out on the Star Wars decor on May 4, and for that never-not-startling illustration of a lion mounting a man, this beer-centric bar may not throw the trendiest parties, but it’s a plucky institution without another queer bar for miles around. No cannabis on the patio, please, but Bob’s Donuts is only a block away.
