We've been invited to a large group event this weekend that starts with dim sum at CBS Seafood in Chinatown. Although we love dim sum we've never been to this particular place. I found mixed reviews (as with all the Chinatown dim sum palaces) here on the board, and nothing recent; but the choice of restaurant was set by the group, so we can't change it and we want to make the best of it. Are there any particularly good dishes there, or anything we should avoid? Thanks.
