Cape May at the BC is a good buffet with a big variety.
Captain's Grille at tha YC is a good buffet, a bit smaller than Cape May. They also have a menu to order off of.
AK has what we think is the best character breakfast on property at Tusker House.
Epcot has Princess Storybook @ Akershus Royal Banquet Hall in Norway WS. As was mentioned Cape May Cafe has a pretty good character breakfast & is very close to Epcot.
We haven't tried Hollywood & Vine at DHS. You could go to CMC from DHS also.
Kouzzina on the Boardwalk gets very good breakfast reviews, & is accessible from Epcot or DHS. This one isn't a character meal.
We loved Tusker House and are planning a return visit this year. Good selection of food and the characters were great. Service was also really good the guy that waited on us was awesome but then we found out he was a classic car geek like us so it made it even more fun.
Kona Cafe at the Polynesian is one of our favorite breakfast places both at WDW & anywhere!
Boma has a great breakfast buffet at the Animal Kingdom Lodge (just a 3 minute bus ride from Animal Kingdom Park). The goat cheese scrambled eggs are delicious!
Crystal Palace in MK has a pretty terrific breakfast as well.
Cape May is a great place for breakfast and is near Epcot and HS. We also really enjoy 1900 Park for breakfast which is a monerail away from MK or Epcot.
We like Akershus for breakfast at Epcot, Tusker House at Animal Kingdom, and bagels and/or cinnamon rolls at Starring Rolls at DHS. The last isn't sit-down, but there is some nice cafe seating outside if the weather is cooperative.
I agree! i totally forgot about that one. We LOVE Ohana breakfast! the food is great, atmosphere is beautiful and relaxed, and the characters are a lot of fun.
