I took my daughter there on her 10th birthday, she ordered off of the kids menu (and they charged me a child's price). We had the breads to begin with, then she got 2 dippers, side a of fruit, and we requested a side of scrambled eggs- which they brought at no extra cost. We were there on the first day it was open so not sure if they watch this stuff more closely now, but since it was a set price I was under the impression that you could order whatever extra side.
We have been to other Disney restaurants with a very picky adult and she ordered off of the kids menu at sit down restaurants all week without a problem. They just brought her double-sized portions of pizza or chicken nuggets.
Hope that helps!
