We ate there for the Christmas one. We really enjoyed it. We thought the food was very good. The "adult" buffet had lots of great meats and sides, and the "kids" buffet also had a good selection of more plain foods. The characters were fantastic. They have new, fancy outfits for the meal. It seemed less hectic than Chef Mickey's because there was no singing, dancing, napkin twirling, etc.
My DH was mad that I cancelled Cape May in order to eat at Holiday Dine, but I thought it was a great experience and was really glad we did it.
