I happened into this strip-mall on the south side of Garvey just west of New Ave., and saw its storefront emblazoned with about 20 Chinese signs and a single English word: "Szechuan". Since that's a good enough recommendation for me to have lunch there, I can report that this place a) exists and b) is worth a try.
I had "Lamb with Szechuan Sauce" thinking it might be stir-fried lamb with Szechuan peppercorns, which it wasn't. It was stewed lamb (mostly meaty ribs) in a red-peppery broth with cabbage. Almost like Szechuan birria (please, do not launch a food truck based on this this). Came with a nice app of shredded potatoes with said peppercorns, so I know they've got them around. Waitress/owner? speaks no English except for the term "ice water".
Quite a few items on the menu that I haven't seen anywhere, so who knows what this place can actually pull off. The English translations are useless, but just for fun, milk batter with cabbage, shrimp with lily, braised fish tail, braised chicken with wine and basil, and plenty of random names "yang chuan noodle", "long jing shrimp". If anyone can translate/interpret these, along with "noisette pork", I'd be grateful!
