We did lunch at chef mickey the second year of
free dining (and I believe the first year they offered lunch)
First, I don't know if it has changed, but NO ONE knew about lunch! The only part of the restaurant they even had open was the little section in the back by the bathrooms, that was it, and it was not even full.
Honestly I don't even remember much about the food, it was good. But, the place was EMPTY (I think we counted at one point there was less than 8 tables at the place with people in it). The characters were amazing, it was one of most favorite disney moments.
We spent about 2 hours eating, and probably 1 hour 45 minutes playing with the characters. Pluto, sat on the floor with my 3 kids, and my friends 2 kids and played peek a boo with a napkin for at least 25 minutes (at least). My youngest was a little scared of pluto, and I kid you not, pluto played with her until she quit being scared. Now, pluto is her favorite.
Chip, dale and mickey tied minnies apron up to one of the chairs, and then made me untie it. They made train tracks with all the sugar packets for my friends sons train. At one point goofy just leaned up against the wall that is near the buffet and stood there for about 15 mintues.
This lunch was probably one of our single most amazing disney moments we have ever had. The character interaction was amazing, and well, the food, like I said was well, food. I really don't remember being disapointed in the food!
So, if you can book this lunch, jump on it. Don't know if word has gotten out about the lunch, but when we went no one knew (they also extended breakfast at the poly really late the year we were there too, and we had an late late breakfast, that was also empty and the characters were super fun there too)
