Lots of people like the Kona Cafe at the Polynesian. I've also read good reviews of Boma's breakfast buffet at Animal Kingdom Lodge. You can see both menus at wdwig.com.
If you'd like to end with something truly Disney-ish, I'd recommend 1900 Park Fare. Alice, Mad Hatter and sometimes Mary Poppins and Pooh (or one of his friends)- Yay! If you don't like the idea of dining with some Disney pals I'd second the suggestions of Kona or Boma.
