We did have pretzels, sometimes ice cream

, some fries- not the best diet in the world- but, hey, we were walking 9 miles a day. Plus, they had the trail mix, granola bars, etc. in their fanny packs.
For sit down meals- hands down- Chef Mickey's wins in our opinion. There was something for everyone. The kids buffet was lower, so they could get their own stuff, the desert was great...... The Whisperin Canyon Cafe was good, too. As was Crystal Palace. We also ate at the Teppanyaki Grill (sp?) in Epcot and weren't that impressed. The Japanese restaurant around the corner from our house is better. However, I know a lot of people LOVE it there - so maybe we just had a bad day there. We also ate at the Prime Time Cafe place - while our waiter was "okay", the food wasn't that great. I wouldn't do it again. But, I know a lot of people LOVE that place too. Another place we REALLY liked was O'Hana's. We had a PS for a time when the fireworks were going off and got a window table. So, it was fantastic. There's a ton of food, activities for the kids. Would definitely go back. We did lunch at the Liberty Tree Tavern - mostly because I always at there as a a kid. It was nice for the memories. But, we wouldn't back.
I tried to book the last lunch time available some days - because you get the same stuff, but it's cheaper.
I hope some of that helps!
