Hound from Manhattan seeks Flushing Chinese Advice

Instead of a vacation trip this year, I am planning to do various New York things. These include some trips to the Flushing Chinese, area, often praised on the Manhattan board. With all the many postings, I would appreciate your opinions on the 1 or 2 dim sum places to definitely go to, the food court (mall?) and best places/dishes within it, 1 or 2 best restaurants. If there are things you think are particularly interesting to see other than just the atmosphere on the streets, I'd appreciate that, too.

Thank you very much!
