It is not the best breakfast buffet at WDW, but it's decent. And there are Mickey waffles!
And, it's the only character meal where Mickey & Minnie are together (along w/ Donald, Goofy, & Pluto).
So breakfast at Chef Mickey's is a "must-do" for us. (But I wouldn't want to have dinner there - just breakfast. I figure, it's pretty hard to mess up breakfast basics!)
I also like that it's in the Contemporary Resort. The monorail runs overhead, & it just feels very "Disney" to me... especially on a bright, sunny morning!
