greg, you should try heading out of the Marina, I'm with you, everytime I party there I end up slapping someone's teeth out. People are a lot less pretentious in every other neighborhood, if you're out in NB try Columbus Cafe, for some reason theres always hella hoes in there at like 9:30pm, also theres Mojitos which is pretty poppin and NorthStar. Chicks in the Mission arent as uppity, your bound to get laid after going out there 3 or 4 times, they probly aint as pretty though.
Nob Hill I guess the spots to go are Shangai Kellys, Tonic, Vertigo, none of them are really hip hop joints, but I swear to god these places are PACKED with beautiful women for some reason.
Mission Rock was the shit back in the day. I remember seeing Mac Dre's last concert in SF there...
