To me, breakfast is breakfast. The characters are what make this meal.
However, dinner is different from other restaurants. The meats they bring around to you on skewers are really good, and you have quite a variety in the sides. They will also bring french fries for your kids if you ask for them. AND if you make a later ADR, you can watch the MK fireworks during your meal or plan it so you can go outside to the beaches at the Poly and watch from there.
They also have a singer and kids games during dinner. It's a little campy, but if you're a child at heart, it's fun.
