Even though this is a simple place, Earl of Sandwich at DTD has delicious breakfast sandwiches. It might be nice to take a leisurely walk over in the a.m. and pick one up. They are cheap, too!!
We have eaten at Cape May (character breakfast buffet) but still the food is rather tasty for a character breakfast. We sampled the Grand Floridan Cafe
(I think is the name) once. Our breakfast was delicious! Starring Rolls at Hollywood Studios has a quick and tasty pastry-type breakfast.
Although we don't do that many breakfasts (always rushing to the parks), we have enjoyed the ones we've tried.
