I see you will be staying at POFQ. If you will have use of a car, some resorts have good breakfasts and I agree with the other posts thus far:
Grand Floridian Cafe, Boma and Kona Cafe for quieter breakfasts.
If you are stuck with a theme park breakfast and want characters, my choices would be Tusker House, Akershus and Crystal Palace, as already mentioned.
