I've had some wonderful Chinese banquets in the East Bay, at Great China (both pre- and post-fire) and China Village. What places in San Francisco would be comparable in quality, and similarly priced or lower, for a group of 15 people?
This would be for dinner, not daytime dim sum.
I looked into Great Eastern, but the reviews were unimpressive, and R & G Lounge recently had a very low health inspection score of 66(!).
