Although, the kids in my family are quite a bit older than your girls we've always really enjoyed Coral Reef. My brother is a fairly picky eater and this is the restaurant he requests every single time we visit. For me, my (current) favorite TS is Yak and Yeti in Animal Kingdom. The Pineapple Won-ton dessert is a must try! Finally, I've never been, but I've read really good things about the Akershus Princess Storybook Breakfast. If your girls want to meet the princesses this seems like a nice alternative to dining in the Castle.
