While Cape May is a nice character meal, if you're looking for some delicious food, one of Disney's "hidden secrets" is Yacht Club Galley. They serve a buffet plus off the menu choices and the food is excellent. Atmosphere is very nice, usually not crowded and service also excellent. The buffet is not huge like Chef Mickey, but definetely adequate.
We've tried Spoodles for breakfast and didn't care for it, many people like it, maybe we ordered the wrong thing.
We've also tried Fresh. This is a nice buffet, but it's been a while since we've eaten there and I've heard it's changed some. They make your eggs, etc, right in front of you while you stand there and also have fresh juices, (some wacky combos), and nice breads, muffins etc. We're eating there again in October since my sister's friend wants to try it.
Cape May has good food too.
Our personal choice of all would be Yacht Club Galley.
We will be at the BC the end of this month. I'm not familiar with the different restaurants/quick service choices for breakfast in the Epcot area. DH likes a full traditional breakfast but is willing "pick" sometimes. I see that both the Dolphin and Swan serve breakfast buffets, how are they? Spoodles for breakfast? Cape May Cafe? Any suggestions would be appreciated.
On the YC side as well, there is usually a little nook off the lobby which has cereal, bagels, and coffee in the morning. If you were to walk to the Boardwalk, Spoodles has a sit-down breakfast and there is the Boardwalk Bakery for quick service (if that's what you want to call it considering it's always packed 
in the morning!!! ) I've never really ventured into the Swan/Dolphin so I can't advise you there... GL and have fun!
