I have to agree with Ohana's. If you have little ones, they will love Chef Mickey's and all the chaos. If you have older kids, they will enjoy Ohana's more. I have a brother who loves CM - I've been there once with him and that was enough. I don't feel the need to go back - even though he and his family do every year. This summer we are eating at Ohana's.
IMO...O'Hana's! Better food, a sit down meal, and a great view of the Castle! My dd enjoyed the coconut races. At CM there was a lot of chaos, and we missed some of the characters when we were on line for food.
