We have done Chef Mickey's two times (last year and just this past week). There is plenty of food to choose from, so I'd be suprised if there wasn't something for everyone. They have a great fruit selection, your usuals of bacon, sausage, waffles (Mickey shaped), pancakes, eggs, cheesey-bacon-egg-type casserole things, homefries, all kinds of cereals, some vegetable lasagna (I know, breakfast, but they did have it), and they even have pizza and PB&J pizza (looked good, but my kids didn't try it), they have donuts, pastries, etc., etc.
It is expensive for breakfast, but you are paying for the characters so that is why it is more expensive than a normal breakfast buffet. We love it. It is nice to have Mickey and Minnie and Goofy and Pluto, and Chip and Dale all come right to your table. They also take your picture when you come in and then bring it to your table if you want to buy it.
