Jiko's is my new Favorite at Disney. If you sit at the 'Cooking Place' you get to watch the chefs prepare the appitizers. They also chat with you and make suggestions if you ask. Sanaa is also good with a large selection. Boma is next on my list to try, I keep read great reviews for this buffet.
My other suggestions are:{Do every trip}
Kouzzina by Cat Cora, at the BoardWalk (BWI)
Ragland Road, at DTD
Mama Melrose, at DHS
Via Napoli, Italy-WS-EP
Note: Even though I have so many favorites, I always try to do one or two new places each time I go.
