Pricing is based on age. But he can choose from either menu. They will make an adult sized plate from the kid meal items if that's what he chooses. They are very accommodating in wanting people to find something they like to eat. My daughter wanted to try the snails on a prior trip, but didn't like them. Certainly didn't complain, just left them uneaten (minus one!). The waiter noticed and insisted on getting her something she wanted. Brought her a nice adult size plate of fruit or something. But yes, we paid the adult price.
