I was actually able to have a pretty solid meal at Nine Dragons yesterday before IllumiNations and after discount it only cost $23 for my meal. Sure, expensive for Chinese Food, but it was good, we walked right it and were seated immediately (no reservation) and the service was great as well as the quality being well above a quick serve despite the price being similar.
Now if we're talking some of the more expensive WDW restaurants (and overhyped) like, say, Le Cellier, then yeah. Le Cellier used to be enjoyable, but now it's just living off of it's former reputation and the prices are ridiculous. Want to do a character meal at WDW (likely with a family of 3 or 4 minimum)? Get ready to shell out $200+. Etc, etc.
There are a few places like V&A's and Tukami Tei that are worth the splurge, but on the whole, the food at WDW isn't worth shelling out the money they are asking.
