was it Alioto's?
just a tip: anyplace thats CROWDED is a good place to eat! seriously, those places are crowded for a reason.
I went to the Wharf and had an awesome bowl of clam chowder and it was like a glorified sidewalk stand and you sit on bar stools and man! was that place CROWDED! but the chowder was sooooooo yummy, and you get crusty french bread and its just the best

I think this is a picture of the place, sorry its not color:
another tip: the "walkaway" stands give you food that is every bit as good as the sit down restaurants, and for less $$$
