Hi there. My husband and I will be passing through the San Francisco area on a Wednesday. We have all day and would like to experience some local favorites. We generally tend to meander, and we'll be meandering from the north to the south over the course of the day. We're up for anything. I've checked some of the "Best Of" threads on the San Francisco boards, but I thought I'd also specifically ask you Chowhounds out there: if you only had one day and wanted to experience San Francisco through its food, where would you go? Anything goes--we want to eat like locals, not tourists, so off the beaten path would be just fine with us. Thanks so much!
