If I had to choose only one, I would choose Donald's Safari breakfast @ Tusker House in AK!
The atmosphere and service were great. They buffet was delicious with so much variety and food I had not seen at some of the other buffets, and the special juice they serve is so delicious! The characters (Donald, Daisy, Mickey, and Goofy) were a lot of fun and one point they take all of the kiddos to parade around the place (no kids here, but really enjoyed watching the interaction between them and the kids... true Disney magic happening all of the way!)
After breakfast we headed right to the safari, entrance very close to the restaurant, and we saw tons of animals out and about. Great start to our day at AK!
