Known locally as the gay “Cheers,” Twin Peaks was the first gay bar in the country to unblock the floor-to-ceiling windows and let the world see just what was going on inside. It sits at the corner of Market and Castro, the true heart of the gay community. In a culture that often worships youth and beauty, Twin Peaks is an oldie but goodie—and tends to attract an older crowd. The 1880s building survived the earthquake and recently gained historic landmark status.
