This is fun night in the Castro and we love to enjoy night with our gay brotherhood. Come here and let's have a fun night in the gay town! The Castro District, in Eureka Valley, is synonymous with gay culture. The gorgeous atmosphere is attractive. Revelers often spill onto the sidewalks at numerous bars, like Twin Peaks Tavern, whose floor-to-ceiling windows were revolutionary when it opened in 1972. The lavish Castro Theatre and the LGBT Historic Museum are also found here, as are homey restaurants.
