I love the Dinner. Always try to make it there whenever i'm WDW. I haven't tried the breakfast yet. But i'm sure it's just as good. They did a special on it a couple weeks ago on the Food Network. They have such a variety of food for Dinner, that it's hard to pick a favorite.
As the Above Poster reported, I'm also a big fan of there mashed potatoes. - But I usually at least try to sample quite a few items from the menu @ Chef Mickeys.
You won't be Disappointed.
