My wife and I aren't the stereotyicpal "Disney nuts" one would expect to find around here. We didn't wear the bride and groom Mickey ears during our honeymoon becuase we thought they looked silly (although I have grown to second guess that decision since I started hanging out here).
Anyway, we still had a great time at Chef Mickeys. It was one of the highlights of the trip. The food was nothing exceptional - typical breakfast buffet fare. But we really had fun with the character visits.
A couple of other notes, be careful of the picture packages. They will take your picture in front of a big cardboard plate. Then they will drop off an expensive package at your table. It's kind of a high pressure sales tactic and we fell for it. If you want the pictures, fine. But don't feel pressured. You don't even have to pose if you don't want to.
Also, frequently there were long lines in the parks to meet the characters. And every so often, the lines would be cut off so the characters could go do parades and things. So we felt guilty taking up a spot in line that would mean a child wouldn't get to meet a character. As a result, we generally didn't wait in lines in the parks. In the character meals, you have no such worries because the characters hit all the tables. It was a guilt-free way to meet the characters.
Enjoy!
