Chef Mickey's for dinner is a loud, insane party. Having said that, it is a good way to see the main characters.
And, we did it in September and were pleasantly surprised by the food. We took my 4-year-old niece for the character interaction. We had a family group of 11. It wasn't the best meal of the trip but there was meals that were considerably worse foodwise -- Liberty Tree Tavern for dinner comes to mind immediately.
What did we like about dinner at Chef Mickey's? We went on rib night (whichever night that is) and the ribs were quite tasty and far better quality than the ribs at HDDR. While we're on meat, the prime rib was only passable, at best.
They also had an unlimited peel and eat shrimp bowl. I'm not a huge fan of peel and eat shrimp, generally, but this was fresh and tasty, with no discernable vein (can't stand eating the vein) and a zingy cocktail sauce.
Some of the cheese, olives, etc. were fine. We basically avoided casseroles, potatoes, chafing dishes, etc.
Salad bar was fine and the kids' items were as expected.
Finally, we enjoyed the desserts. They had some kind of key lime tart that was nothing short of delicious. And, everyone enjoyed the make your own sundaes.
Will we go back? No. Once was enough. But, was it a nice enough surprise we'd recommend it to others? Yes.
