It was very good.
I did not care for some of the food which caused me to ask repeatedly for more. I do not like to waste and didn't like how when you ask for more, they bring you an entirely new plate. They wont bring more of just what you like (it's all you can eat mind you) and bring you a new plate with EVERYTHING on it, which I know causes a incredible amount of waste. Also, because they bring you an entirely new plate, you only get a very small portion of what you wanted the most of, meaning you have to yet, ask again. I felt guilty asking so much and then felt guilty that I was wasting so much.
The food I did like was great, and great all you can eat dessert! YUM!
Our waitress was very good, except, unfortunately like most disney resorts, I felt a little rushed by our waitress.
The nice thing is that in most restraunts, even the nicest, you are crammed in among other people so close that they may as well be sitting at your table with you. Not much intimacy at most disney restraunts. I was there with my wife on our 1 year anniversary at the Le Cellier and though I loved it and we are going back this year for our anniversary, the people were so on top of you that I felt odd talking sweet to my wife with all of those people there.
The Garden Grill DOES give you some privacy as you are in your own booth and the backs of the booths are high so that you do have your privacy. I really LOVE the privacy.
