Chef Mickeys!
For breakfast, it's a tie between Chef Mickey's and Crystal Palace as the best character breakfast in WDW. I love the selection at both meals.
I was slightly disappointed with the meal at 1900 Park Fare, It was basic. There's just more stuff at the other restaurants. Plus I love that they have their special items. Crystal Palace has breakfast lasagna and Chef Mickey's has breakfast pizza - both yummy!
I was also surprised that there were so few characters at 1900 Park Fare. Mary Poppins and Bert are outside, while inside was Alice, Pooh and Tigger. I love how at Chef Mickey's you get the whole gang and at Crystal Palace you get Pooh with all his friends.
I would only go to 1900 Park Fare if you have a little girl dying to meet Alice.
For atmosphere, Chef Mickey's is loud noisy and a party every 30 minutes with napkins waving in the air. Lots of fun. I found Crystal Palace fun, I thought Pooh's parade with the kids was a nice touch. Overall, it's much quieter than Chef Mickey's. It's also the most beautiful restaurant out of them all.
For dinner, I've only eaten at Crystal Palace and it's by far my favorite dinner buffet. Haven't done Chef Mickey's yet.
