If you are looking for a character meal, Tusker House is the one and only character buffet we've found where we actually enjoy the food, novel concept huh ; ) Seriously though it was a good mix of regular breakfast offerings, but all some unique african items that make it worth the while. You also get Mickey, Goofy, Donald, and Daisy in safari gear which is lots of fun.
If you're up for something without characters I think Kona has the best breakfast on property hands down. Tonga toast, macadamia nut pancakes, pork eggs Benedict, the list goes on and on....
