We have PS for this next Thurs night. However, I am still highly considering cancelling it. It is pretty expensive, which didn't bother me at first.
After hearing alot of reviews, I hear that it is hot and people are sometimes rude - taking other places at the tables, etc.
My 4yo eats like a bird and to spend $25 on her for a meal ? It's too bad because I was really excited about it until I heard from others.
Page 7 of this board (Disney Restaurants)has 2 threads about it, also check the "Camping" board.
We were unable to get PS for Chef Mickeys. We do have a PS for 3:00 on Friday at the Garden Grill for the "Ice Cream Social", which is an ice cream party with the characters. It is only $6.95/person. We have never been, but it sounds like fun. I mean with ice cream and Mickey - sounds great to me. The kids are really excited.
Good Luck!
