A nightlife institution, the EndUp is exactly what it sounds like: one of those all-night nightclubs in San Francisco to end up at after all the other clubs and parties shut down. The facilities are comfortable but not fancy. There’s a heated patio that gets bumping, a small dance floor, a fireplace. The crowd includes everyone from gay to scruffy Burning Man hip to dance floor divas in their slinky Prada gear. Saturday night keeps right on going through Sunday and into Monday, and has for thirty years. Fridays from 10pm to 6am are Fag Fridays, immediately followed by the mother of all after-after-after parties from 6am-1pm. The best, however, is Sunday Church, the original T-dance that gets bumpin’ at 6am. Grab a Red Bull and stick around. Fag Friday segues early Saturday morning into a mixed party that lasts until 4pm. Or arrive as late as you want on Saturday night and stay until Sunday. You can even round out the weekend with the notorious Sunday night dance party, starting at 8pm and continuing into the commute hours. You name it, you’ll find it here. Drag queens, Gucci boys, slaves to the new economy, party promoters, trannies, and girlie girls-and that’s just the line for the bathroom.
