On all of our longer cruises (2 Med, 1 Baltic), there was the usual restaurant-specific menu the first three nights, then some of ones you see on shorter cruises, like Prince and Princess, Captain's Choice, etc. but there were always 3-4 that were themed more to the location. So one of the Med cruises had a Greek menu one night, the Baltic had a Scandinavian inspired menu, etc. All three cruises had different menus every night without any exact repeat appetizers, entrees or desserts. Only one night did we not go to the MDR for dinner and that was when we were in St. Petersberg overnight on the Baltic cruise and we, along with a lot of others, had late-night excursions. When we got back to the ship, they had set Cabanas up as a hot buffet for several hours; we ate there around 10:30 pm.
