We do Chef Mickey's every trip. I like that it is buffet, and the food is always great when we go. Bring a good appetite. They have everything from salad, fruit dinner and dessert and it is all good. The character interaction has always been good. We see Mickey, Minnie Chip, Dale, Donald, and Goofy.
I have to admit that I have never done LTT, basically because with my kids, it's easier to do the buffet. My older DD is very picky. She loves mac and cheese at home, but will not eat it out unless it's Kraft. At least the younger one eats it all.
I am getting close to my 90 day window. We are hoping to get CM on the first night. It's become a tradition for us.
