Royal Caribbean cruisers can no longer get a grilled chicken or salmon every night for dinner. Same for shrimp cocktail and onion soup now that the line has finished the rollout of its new dinner menus that have seen the elimination of the classic dishes section.
Instead, each night's menu is themed and may offer one or two items that used to be on the classics menu – but not the same item each night.
Off-menu order is not permitted, as is clearly displayed on the menu: "Requests for items that are not on this menu can only be accommodated for allergens or dietary restrictions."
According to a discussion on Cruise Critic, efforts by cruisers to make changes to menu items or ask from something else are mostly being denied, unless it something simple like asking for a dish without the sauce or swapping a side from one dish on the menu for the side from a different dish.
If a cruiser doesn't like what's on the menu at all, they have only a few choices. They can ask for a side that's listed with one of the dishes on the menu. They can ask for veggies – again that are already on the menu listed with something else. Asking for the kid's menu is another option.
