My better experiences have been with the UWS location. As I mentioned upthread, my experiences of the Chinatown branch were in the big hall, usually when I took groups of people there for a Lunar New Year celebration (it was that if I was in NYC, or China Pearl if I was in Boston), more for the atmosphere and spectacle than for the food (some dishes were very good, but many were, as you say, just OK). I haven’t been to the Chinatown location since the big hall closed, but have had the UWS food about a dozen times in the last 3 years. As I said, it’s been improving and is now, as @Saregama observes, quite good overall.
