Yes, there is a box to check…..but it doesn’t mean a darn thing. As suggested, make it know to the restrauant manager and they will take good care of you. The buffet is iffy. I am celiac and have gotten poisoned twice in the buffet, despite having the chef walk me around and show what’s safe. I suggest you stick with the MDR. Good luck, and understand….it is all on you. Be vigilant and assertive,
