Yes, she can order off the kids menu. My 10 year old eats very little, and she's picky. In some TS restaurants, she was offered both an adult and a kids menu. When they didn't offer both, we asked for a kids menu for her, and we were always given one. She usually chooses one of the following: a kids meal, an appetizer or side off the adult menu, or her favorite "an extra plate," which allows her to eat a bit off of all of our dishes. We've always been accommodated and never given a hard time at WDW (one of the reasons I love the world...).
