I don't recommend the Garden Grill at all. We went last December and didn't have a good time.
First of all, the food was terrible. All of the food on the family platter they bring to the table was very bland. No flavor at all. Only my DD's food was decent and therefore, DH ordered a child's meal for himself.
Mickey mouse was out of character and only spent a minute with our table. Chip also seemed to be in a bad mood. Dale and Pluto were great though.
Service was pretty good. I did not like the rotation of the restaurant as when I got off, I was off balance for a few minutes.
We also had to wait at least 15 min. for our table even though our ADR was for 3:40pm and many tables were empty.
I did not care for Chef Mickeys either, but it was much better than Garden Grill.
