I wouldn't eat there without kids. There are much better restaurants in WDW for adults to enjoy. We ate there this past trip and the service was terrible.
While the food was good (when we finally found our waitress and got it) the atmosphere is very loud and there is a lot going on.
I know alot of people on these boards really love this restaurant. I am glad we tried it on our last trip, but we won't be returning.
If you have ever been to a Dick's Last Resort type of restaurant, then that is what I can compate WCC to.
