The kids meals are, in general, pretty disappointing---even for kids. You probably *will* be able to order them, and probably *won't* be given any grief for doing it, but do you really want to? I wouldn't.
At TS locations, consider ordering an appetizer rather than an entree. That's a nice light meal that actually tastes pretty good. At CS locations, order simply---even though the menu board lists entrees with sides, you can ask to have the side left off and save a few bucks along the way. We often get only 2-3 orders of fries between the four of us, for example, and that's plenty.
