We have been to Chef Mickeys three times in the last eight years.
I can say that the experience was consistent. The characters were fun, and the food was only so-so. Breakfast each time.
Actually each time the food has seemed to be less palatable. Not that is bad, but I would expect more of Disney. I fugure we were paying $10 for the character experience and $6 for the food which was about what it was worth. If you get caught up in the character experience, then you don't mind the average eating, but don't expect a gourmet experience.
