I had special menu ..you get the menu a day or so before check off what you want they adapt the item to suit your needs like sodium free gluten free etc
When you give your room number at the reservations desk you are flagged that you have a special meal they bring out the pre filled in menu & give it to the waiter that escorts you to the table your meal is served along with other tablemates course by course
No one needs to know you have a special menu
Some waiters will confirm with you that items are what you ordered to be sure that is no issue
