San Francisco Bay Hobby/Electronics Stores?

Hi everyone,

I'm in San Francisco for a few days for RoboGames and thought I would visit some local hobby shops. Anyone know where the good ones are? I'm staying at Fisherman's Wharf, so, if it was close it would be great.

I also might need some electronics parts for my robot. I know theres a radio shack around here, but, any personal picks?

Thanks,
