Staying at a hotel near the Embarcadero, will have a 3-day muni pass, so getting around is no biggie: I need honest to goodness recommendations for great Dim Sum in your fair city. Nothing touristy please, my favorite spots in London, Seatle and Toronto are basement dives under mom-and-pop restaurants in alleys where the food is great, place is full of local workers, English is just an aid to sign language, and prices are reasonable.
So, what you got SF? why and where? and best times to hit them.
