We recently did both on the same trip. We did goofys for dinner and Donald’s for breakfast. We enjoyed both, but really had an amazing time at donalds.
At donalds they have hot breakfast food, some pastries. I had a plate with a Mickey waffle, Mickey pancake with whipped topping. So good. There is also this Mexican egg tortilla bake thing- not sure the name, but its my favorite. We went last year too when it was mickeys breakfast and the food was the same. Also what makes donalds special IMO is it is the only place in the whole resort that has stitch. Unless you have the Disney credit card and get lucky with him at the chase meet and greet. We do donalds for that reason alone. Daisy, Minnie and Donald were also there.
Goofys kitchen for dinner had Mickey at the front and goofy, Pluto, chip and dale and Minnie.
