Can anyone recommend a good Cantonese restaurant (or three)? Suggestions for dinner, noodles, and/or dim sum would be enormously appreciated. My husband -- who is of Cantonese descent -- and I recently moved to Chicago and we have not yet found a Chinese restaurant that's really worth going out to. We live in Streeterville (which I suspect is a big part of our problem) and don't have a car, but we're perfectly happy to get on public transportation for a superlative meal. On a friend's recommendation, we took a jaunt up to what is apparently the "New Chinatown" area of the city, but everything seemed shut up tighter than a drum at 7:30 on a Friday night. In any event, we'd be most grateful for any suggestions!
