We had a reasonable meal at this old favourite last night.
Starters were crispy cauliflower (fantastic), vegetable dumplings (OK), hot and sour soup (not the best I've had) and salt and pepper squid (good). The mains weren't quite as good - my friend was very disappointed with her crab, which she said was mushy, and there wasn't a whole lot of meat on it. I ordered prawns in a hot and sweet sauce which, again, weren't that much to write home about. The Szechuan crispy beef was a bit disappointing too - it definitely lacked spice, but I must add that I'm not an expert on Szechuan cookery (yet - I have just bought the Fuchsia Dunlop book). The high points were the Tibetan lamb, which was spicy and flavourful, the braised aubergine, and "dragon broccoli", which was deep fried and really tasty.
With two bottles of Sancerre, three desserts (which I didn't try) and service, it came to £40 a head.
The food at Haozhan on Gerrard St is much better, imho. but I prefer the atmosphere at YMing, as the service is always very friendly. A pleasant way to spend an evening with old friends.
