I haven't been in quite a while, but my opinion seems to concur with many others here. They're charging pretty high prices for food you can kindly call mediocre at best. This is especially true if you're more used to paying "take-out" prices (at least in my neck of the woods, paying to dine-in usually costs a couple of dollars more).
If you HAVE to eat Chinese food, and you definitely don't want to go off-site, I doubt it'll give you searing abdominal cramps, but I also don't think you'll feel like you got your money's worth, either. The Unofficial Guide to WDW crucifies Nine Dragons, though (not just the reviewers, but readers who can send in a thumbs-up-or-down card on any resturant in WDW, plus comments, give this resturant pretty low marks), and it gives you a list of nearby restaurants, some just right outside of Downtown Disney, that serves better Asian food.
