My favorite in Epcot Resort area is in the Swan at Garden Grove Rest. No direct way to get there from the Contemporary and long walk from front of Epcot, so maybe bus to studios and boat over to 1st stop Swan/Dolphin, or Uber. After breakfast boat over to Epcot International Gateway entrance. Check out the menu and prices, a la carte or a fantastic breakfast buffet, character on meal weekends only, a must do every trip for us.
I know it isn't the most convenient but the food is very good, Les Halles is very good for quick service
