I have never had a problem, kids like the kid food, not the adult food, I don't think it matters really that much. I think the rule is really so that adults don't go into Le Cellier and order a kids meal or try to order 2 kids meal and get off cheaper, you know. My philosophy is I am not paying for an adult meal that my kids don't like when there is a perfectly good kids meal that they will scarf down. I have even ordered kid meal (at CS) for myself if it is what sounded good, and wasn't up for any other of the adult food.
My thought is, I am getting exactly what I paid for, who cares who eats it?
