I have always just eaten breakfast at our resort. Coronado springs has a great counter service restaurant called Pepper Market which is more like a TS, but only uses CS credits.
A lot of people rave about Tonga Toast which you can find at Caption Cooks at the Poly as a CS or at Kona as a TS.
We love getting breakfast at Main Street Bakery in the Magic Kingdom. We only ever need to use our snack credits and get to enjoy lots of yummy freshly baked goodies.
