Decent Chinese in Hell's Kitchen?
The short answer is no. To my knowledge, the only remaining Szechuan in the 'hood is the very middling Ollie's Brasserie. Its lack of affiliation with the Ollie's mini-chain is really all it's got going for it.
If I'm fiending for Szechuan I trek to Wu Liang Ye (48th between 5th and 6th). Hell's Kitchen (at least 9th Ave westward) is outside their delivery zone. If you're able to meet them halfway in some kind of Seinfeldian delivery coup, do report back.
Moving away from Szechuan, you might want to try some of the noodle or rice dishes at Saigon 48. It's a reliable, Seamlessweb-able Vietnamese restaurant with a handful of tasty Chinese options.
Wu Liang is very good, but also quite pricey. Last time I went and took some friends, they had some sticker shock, and I felt guilty because I had forgotten about the menu pricing there. Food was very good though.
Since we lost Grand Szechuan on Ninth, Hell's Kitchen hasn't been the same. That sounds dramatic. But it's a drag. At least Pam Real Thai is of equal or better quality (please don't flame, I know it's not Chinese).
