Does anyone know the best place to buy live crab in San Francisco? I just got back from the waterfront where I was disappointed to find that the seafood stands were all sold out by 3 PM. They also mentioned that the fisherman are technically prohibited from selling their crabs directly to people at the wharf. Will they do it anyway? I also keep reading that Asian markets are good places to go, but which one? Any help anyone could give would be much appreciated.
