83 Proof, the unmarked FiDi bar that opened in the fall of 2007, stands alone from the usual San Francisco bars. San Francisco’s choice watering holes are marked by sophisticated libations, sleek design, and in-the-know regulars flaunting off-the-menu speciality drinks, but in 83 Proof, ask the bartender for the cocktail list and he’ll say, “We don’t have anything like that.” Hungry? BYO bar snacks (“there’s a Subway down the street”). But to the raucous crowd of after-work barflies that swarm the place on weekdays starting at 5pm, this is precisely what makes 83 Proof so great. Caramel-hued walls, painted with a bold feather motif-the only decorative element to speak of-provide a warm backdrop for friends and coworkers rehashing the day at max volume.
