End Up is by far the hardest/craziest club in San Francisco. This is a tweaker destination for only those true clubbers. You%u2019ll find a strange cross section of San Francisco here ranging from industry professionals, gay, Marina kids, B&T%u2019s and goth. Despite their differences, their is a weird harmony about the place. Mainly an afterhours club with a decent Thursday night house event. Friday is %u201CFag Fridays.%u201D Saturday will get a huge cross-section of the city in the mix.
