This is going to be really hard but hmm . . basically, me and my girlfriend, avowed NYC chowhounds that we are, are visiting the Bay for about a week . . . I noticed that this bulletin board is not broken down into categories like NYC, but basically, we'd like some recommendations for SF food, on the extremely low and chowhound-y hole in the wall end, and also some nice restaurants which are worth the cost. Looking for hokey wharf type recommendations, proper fish tacos, SF Chinatown goodies that we can't get back in NY, maybe some other random strange and small establishments worth exploring and visiting. Also, if we're on the tourist bent (our first time in CA) in the area, any recommendations in those areas, so we don't get stuck w/ overpriced tourist food . . . thanks in advance; we really hope to leave San Fran with a good culinary impression . . .
