SF Bay Area

Hi, I just moved to Berkeley but I'm planning on moving to San Francisco when the lease is up. Did anyone go to the Chinatown Streetfest last week? I always get nervous trying to speak Mandarin, usually I worry that the person I try to talk to doesn't speak Mandarin... but I loosened up a bit and went for it. Everything went alright, even at my newbie status.

Does anyone know of any conversation or study groups?
