Tried The Phoenix in Chinatown: solid B, some dishes B+. Tried Lao Sezchuan, also in Chinatown: a C, if I were feeling generous (maybe our expectations were too high, given the hype). Tried Big Bowl, the 'chain' on the North side: C+, and not exactly Chinese.
So what do readers recommend for Chinese in this city? Szechuan preferred, but am interested in all recommendations. (Any readers who want to weigh in with recommendations on Japanese/sushi places also welcome.)
UDPATE: Warm thanks for all the really helpful responses already! May I also ask for any recommendations for good Indian restaurants in Chicago, especially if they are also kid-friendly.
