Epcot only has the 2 choices - Sunshine Seasons and Akershus as others have said. However, all of the Epcot resorts have breakfast options and it's only a few minutes walk or boat ride to any of them. Places that come to mind are Captain's Grill, Cape May and Beach Club Marketplace at the Beach and Yacht Clubs, Boardwalk Bakery and Kouzzina at the Boardwalk, and additional restaurants at the Swan and Dolphin.
