Cool clubs or hang out spots in San Francisco / Oakland

Hi peaps,

I'm traveling over to San Francisco and Oakland next week. Any tips clubbing / cool bars I should check out. I'm not looking to DJ I just want to have a great time to unwind after work and on weekends. My music preference House, Deep House, Disco or Techno, but open to going to any good night really.

I hear CA has some great craft beers, any recommendations on that too?

Any record store recommendations? I'm thinking of checking out Amoeba record store. Looks massive from the web site.

TechTools guys plug in here too please, would love to meet you and show some support if possible.

Anything before 21st September 2013 :D

Thanks
DJ Nelson
