I haven't been impressed with either one. I was thoroughly disappointed in Trails End for lunch on my last trip, I'd been there many years ago (15+) and remembered great food. This time, I was shocked, given all the great reviews I've seen on the boards. Just a handful of selections of really bad food (and I have a high tolerance for subpar theme park food.

) that seemed to have been sitting under the lights for hours. Hardly any CMs around. It was like they'd run out of food and no one cared. Obviously they get it right sometimes, or I wouldn't get the raves that it does here. Maybe I caught them on a bad day.
WCC....well, you don't go for the food, you go for the waitstaff's antics. It's a themed restaurant, and if you want to play along with the teasing, napkin waving, stick pony races and singing, that's what it's all about. The food is good, nothing special. Typical hotel restaurant fare, except for the skillet that they're known for.
For a really good meal in that area, I'd highly recommend Kona Cafe at the Poly or the Grand Floridian Cafe.
