Hi Sue
As with the formal nights, keep in mind it was a Christmas cruise, so the MDR had special menus twice, Christmas Eve and NYE.
All the menus had the same 'favorite' items each day.
Breakfast had two items each day that were new.
Lunch had a couple items new.
Dinner had the most variety.
We did see the same dishes pop up more then once but we didn't feel they repeated the whole menu completely. And there were items we only saw once.
So no, I don't think they just repeat the same thing twice, but there is repetition in the dishes for sure.
That said, they did a 'British Pub Lunch' twice, identical menus, but that's more a theme thing then a general recycling I think.
Note: I fell in love with the Mac n Cheese on the lunch menu and strongly suggest you try it if you're a cheese lover 🙂
