Mark, i think the restaurant you are talking about has closed. but for other dim sum recs.
I would recommend Gold Mountain in Chinatown in SF, or Koi Palace in Daly City for dim sum. Koi Palace is great for Chinese seafood, it can get pricey, and there is a very long wait for dim sum. San Tung is a good one, great chinese chicken wings, dumplings, noodles, sting beans, etc. (it's a chinese/korean restaurant )R & G is also a great chinese restaurant in Chinatown -their beef is well known as well as their salt and pepper squid. If you like Chinese desserts, try Golden Gate Bakery. Hope this helps, let me know if you have any more questions or need other suggestions on restaurants in SF.
