It used to be a rough biker bar, but these days you’ll likely see more fixed-gear bicycles than Harleys locked up in front. Zeitgeist serves more than 20 types of German beer, most of them dead cheap, making the dive a favorite among the Mission’s hipster crowd. But it’s the relaxed, gritty environment, somehow untouched by gentrification, that’s the real attraction, especially on sunny days when the mellow beer-garden vibe is in full force in the spacious and very urban backyard. Zeitgeist’s Bloody Mary is the best in the city. Cash only.
