As development in the city center continues at a ridiculous pace, underground club culture has had to spread out to less-frequented areas: Think Dogpatch, Potrero Hill, and Bayview. Interestingly, these neighborhoods have their own nightlife history, which often stretches back to the '90s rave heyday. Case in point is Danzhaus (previously Gingerbread House), a fully licensed dance studio on the outskirts of Potrero Hill that's been serving the late-night crowd for a while now. This year, the place has seen more use by bigger promoters: London Internet mix show Boiler Room used Danzhaus for its first S.F. edition, and Lights Down Low recently turned the room into a massive nightclub for Julio Bashmore. Getting to Danzhaus might be a trek, but it's one worth making.
