I don't think there are two many good choices in Epcot for breakfast since World Showcase doesn't open until 11:00am.
Suggest you check allearsnet.com. Under dining you can view menus.
You may want to go over to the Boardwalk area from the back exit of Epcot (International Gateway). You can take the boat or a short walk to the Yacht/Beach or Boardwalk. There is a character breakfast at the Beach Club every morning. You can have a non-character breakfast at the Yacht Club.
We always enjoy breakfast at Spoodles. It is a few doors away from the Boardwalk resort. Great food and a nice quiet atmosphere. Try their breakfast pizza..........DELICIOUS.....great coffee too.
