We celebrated New Year's Eve at Chef's Mickey. We have eaten here many times and it is our favorite character dining experience. I recommend reservations through WDW Dining. A good idea to call atleast 3 months before your trip.
Goodfy meets you while you while waiting to be set at your table. This is a fun time to get pictures. Once at the table, the following characters visit seperately: Mickey, Minnie, Donald, Chip, & Dale. The characters allow time for pictures and special time with children. This makes the whole dinner/breakfast worthwhile.
The food is excellent. It is served buffet style which includes just about anyting anyone would want to eat - seafood, prime rib, chicken fingers, etc. Be sure to try the dessert section as it has lots of Mickey's favorites.
One other special feature about this restaurant at the Contemporary Resort is the "celebration" time with the characters. The restaurant plays music and the characters dance, sing and wave napkins around in the air along with the restaurant patrons.
We have also been to Chef Mickey's for breakfast and was also impressed with the food and entertainment quality. This is our family's favorite thing to do on our many trips to WDW!
