We have ordered from Chengdu twice since moving to Squirrel Hill. The first time, I wasn't impressed with anything we ordered. It was over-sauced and overly sweet. We eliminated it from contention and kept looking for the best Chinese place in the area.
Three months later and having sampled several other places in the area, I forget that we had eliminated this one already and ordered from there again. I thought we'd missed it and decided to give it a try since it was listed as one of Pittsburgh Magazine's best restaurants of 2016. That list is usually pretty great, but they definitely missed on this one. Attempt #2 here produced another variation of the same overly sweet, gloppy, soggy mess that we got the first time. There was no spice at all on the entrée and the rice seemed old and dry. The wontons were super chewy and did not come with any sauce. It also took more than an hour to get despite being an easy 1/2 mile straight walk from my house. Also, it was delivered by a sullen looking guy with a big growling monster face printed on his crotch. Ick.
