We ate at Chef Mickey's a few weeks ago, and I thought the food was just okay. There weren't as many selections as I'd expected: good salad bar, two veggie dishes, one fish/pasta dish, a chicken dish, a beef dish, and roast beef. The deserts were key lime pie, brownies, and soft-serve ice cream. The quality of all the food was average -- just average. The presentation was somewhat lacking. Frankly, for $25/person I expected more in the way of food.
The character interaction, however, was wonderful! Goofy was the best. He sat at a chair next to us and stomped his foot to get the waiter's attention. He pretended to drink a child's drink (the other family was away visiting the buffet, and my daughters asked in whispered voices whether they should tell the little girl that Goofy'd been drinking from her cup). Mickey, Minnie, Chip, and Dale were also great. Donald, who was the greeter that night, was wonderful too. At one point I took my youngest (age 5) out to use the restroom. We ran into Donald, and they danced. She still hasn't told her Daddy and sister about dancing with Donald (it's our secret), but she has a big soft spot for Donald now!
Would I go back? Probably -- the kiddos loved it. Perhaps we'll try breakfast next time.
