I'm somewhat embarrassed to admit that I and a number of my friends have never had Dim Sum. Naturally the rest of our friends think that we're insane, so we plan to rectify the situation over the long weekend. Unfortunately, most of us are recent college grads, and therefore broke. Most of the suggestions I've seen for Dim Sum are along the lines of, "X is fantastic but expensive", which sadly won't cut it.
We're also hoping to make this the first stop on a day trip into the city, so proximity to public transit- especially BART- is a plus.
Lastly, if it makes any difference, we'll have along at least one friend fluent in Mandarin, though given the way I understand Dim Sum to be served I'm not sure if it that's relevant.
Is there any chance that SF has a restaurant that would be a good fit?
