What's Special About SF?

[badschiraldi]

Hi, I'm an L.A. hound coming up to SF for a few days. I'm living with the wonders of Thai, Mexican, Sushi and Burgers down here. I've previously lived in NY and Boston - so I've had the best of east coast bagels, ice cream, clam chowder, pizza and pasta.

I have spent very little time in SF, and my question is this: what should I be looking to eat that I can't get anywhere else. I have some thoughts: sourdough bread, mission burritos, etc. - but I'm looking for some guidance.

I want to make the most of my few days up in SF (will be staying at the W), and I want to do it right. We are planning on one nice dinner at Bar Tartine (barring other suggestions) but any and all other suggestions are welcome.

Thanks in advance.
