off the top of my head there is a 7-day rotating menu.
>there is the daily favorites served everyday (think beef pork bird fish noodle/vegatarian) and then a rotating menu.
lunch and breakfast are more "repetitive" but that (especially breakfast) is to be expected.
also there is an asian themed restaurant jasmine garden* that is complementary, if you want some variety.
here is the menu for the mdr NCL Menus 2024 · Prof. Cruise, Ship Tour, Cruise Vacation, Cruise Travel, Cruise Menus (profcruise.com)
*just pop in for dessert and try the red bean pie with green tea ice cream; thank me after your cruise 😃
