Well, our absolute must-do from the time I was in MS was the Garden Grill in The Land. We hit it on our honeymoon as well. Unfortunately, when we went back with kids in Feb. they were right in the middle of their refurb. and we knew it wasn't going to ever be the same again.
Alas, it has come to be....all reviews I have read about the new and, from what I've heard, not improved, Garden Grill...prove that our favorite will not be there anymore. We loved the "down home" feel of this restaurant along with the novelty of the revolving restaurant (although they still have that). But I won't waste my money on food that I've heard is HORRIBLE in comparison to our favorite restaurant and how it USED to be....oh well.
Now I would say that this past trip our favorite was Princess Storybook Breakfast. The food was pretty good and very plentiful and the princess interaction was pure DISNEY MAGIC for both my girls (and the adults as well if we'll admit it!!!)
Next time, I want to try Chef Mickey's and Whispering Canyon....
