There is also a breakfast buffet at 1900 Park Fare at the GF with Alice and Mary Poppins. I wanted to do this one, but couldn't fit it on our schedule. Next time, though! It is being refurbished and temporarily relocated, but based on your ticker, it should be back in its regular place when you go to WDW.
We are doing 'Ohana (Lilo and Stitch) and Akershus (princesses, the one in Epcot Norway). Both are served at the table family style, all-you-care-to-eat, not buffets. The menu at Akershus is standard breakfast fare (eggs, potatoes, bacon, sweet rolls, etc), but the menu for the princess lunch and dinner there is distinctly Norwegian. If you end up in the lunch or dinner hour there, you might want to read over the menu carefully first to make sure it's to your family's liking, because the flavors and ingredients are a little unusual (lingonberries, venison, cod, lamb, rutabagas, beets, cauliflower, smoked fish). However, many people love it specifically for that reason. We chose the breakfast because it's more to our taste. We're also doing CP (the buffet with Pooh and friends) on our last morning. Love those character breakfasts!
Have a wonderful time!
