Just a heads-up on Uyghur Kebab, as I haven't been there yet. Isn't this the location of the long-lamented Wong's Eatery? (I still fantasize about the dim sum there.)
Flying Tiger is a about a block further west on University W. We went there on the recommendation of my Hong Kong Chinese co-volunteer, who suggested the garlic green beans. They were great, but salty. Lots of wok hei (something she lamented that they couldn't manage at home) and the ground pork bits were crispy magic.
The hot and sour soup was both hot and sour, with plenty of stuff in it...tofu, pork, various veg, and, astonishingly, the most flavorful, well-cooked shrimp I've had in years. The soup was a bit over-thickened for my taste, but one copes.
Beef with ginger and green onion, one of my favorites when done right, was just ok. The beef was over-tenderized to the point of near-gelatin, but that is kind of fun in itself. Not enough ginger, and the sauce as a bit gloppy.
The server was very attentive and sweet, but the place is, frankly, kind of a dump, and they charge separately for rice and tea. So, a bit mixed, but I suspect there may be hidden treasures.
