I have never been to SF before, I'll be there for Memorial Day Weekend.. I've also never had Dim Sum and I would like to try it. Any suggestions for a first timer? I don't want to travel too far we are staying in Nob Hill, so somewhere in Chinatown would be preferred, since I want to go there anyways. Any other suggestions for breakfast, lunch and dinner in North Beach, Fishermans Wharf, Nob Hill and Chinatown would be much appreciated. I want to get the best of the city while I'm there!
