Count us as guests who think it's very overrated - food is not good and character interaction leaves something to be desired. Although in all fairness to the characters, I have never seen such chaos at the fault of parents who let their children run amock like at Chef Mickey's. Kids were constantly interrupting and bugging the characters - running from across the room, as parents were trying to get their food. We were not impressed at all!
For our July ADR (that was made 6 months in advance) for hubby's birthday, we waited 45 mins. just to be seated, and then dinner dragged on. They messed up my hubby's birthday surprise - server started singing when my hubby wasn't at the table and Mickey refused to come over (the server wasn't sure what to make of that as it was our turn?). Anyway, it was very noisy, food was not that great at all, sundae machine was broken, it was messy, kids running all over, etc. We have eaten at almost every restaurant on property, so we absolutely know what to expect and what to compare to. That being said, my daughter wants to go again (we love the Contemporary), so we are going for breakfast next trip, as dinner just wasn't that great. Our friends who are DVC members like us, prefer breakfast as well.
Hopefully our breakfast experience will be better than our dinner, Tiger
