Our favorite WDW breakfast is at Olivia's. We like the sweet potato hash. Nice friendly atmosphere too.
If you are looking for something "lovely" with excellent service and food also still fairly quiet, our other favorite is Grand Floridian Cafe. Lovely Victorian atmosphere, Maple Vanilla French Toast is yummy, other dishes very good too. I guess this would be my choice if you want a more "special" atmosphere.
I'm not sure though if it will be a character meal when you are there, you'd have to check on that.
Another favorite is Yachtclub Galley, they have a small but very adequate buffet, or choose from the menu. Has always been quiet and non rushed.
We tried Spoodles, but you should probably ask suggestions for foods if you go since we didn't care for ours, but I think I might give it a second chance sometime if I have the opportunity.
