The crab is not to be missed. One block of Taylor Street, between Jefferson & Embarcadero, is full of restaurants specializing in crab. I don't remember which one I went to but it had a rose as its logo. I just went for the plain cracked crab, with a salad & white wine. It doesn't get any better than that.
