We had the Ohana breakfast Sept. 2003 and Chef Mickey in May 1994. My favorite was definitely OHANA for several reasons!!! The food was excellent and we enjoyed the food being brought to the table, whereas at Chef Mickey we had to go to the buffet. We have 2 small DD and leaving the table is inconvenient. Also, the restaurant area of Ohana is MUCH larger and more open than at Chef Mickey. This enabled the girls to get down and dance and interact with the characters much easier. They even had a "parade" around the room with Mickey, Goofy, Chip and Dale. When we were at the Ohana, the characters were at our table so much that it was almost difficult to eat, but I don't remember there being nearly as much interaction at Chef Mickey's.
Alas, my DD are currently WAY into the Princesses, so we opted for the Princess Storybook Breakfast and dinner with Cinderella at 1900 Park Fare this October. I know that I will greatly miss this breakfast .... but, there is always next time.
:p
Only 8 days until our next WDW vacation!!!!
