Open Thread Thursday

My beloved Farmboyz are heading out to San Francisco a week ahead of me this weekend. I was about to spend a couple of hours writing them a long list of must-sees, but since it's been almost nine years since I left, I decided to throw it over to you guys. Key words: art galleries, architecture, staircases, indie theater, and funky restaurants. And maybe most importantly, what's your favorite place in the Cool Grey City of Love?
