We did this breakfast on our last trip in January. The food was pretty good. There are several different buffet stations in one big room including all the Disney standards such as Mickey waffles, etc, etc. plus others such as cereal, yogurt & granola add ins, Fresh Fruit, etc. The juice is a tropical fruit juice mix.
The characters rotate as they do in other character buffets and they have a little "show" where the characters recruit kids to come into the center of the restaurant and play instruments and dance around.
If you have any other questions, feel free to ask!
