Cabbage rolls (called sarmale), stuffed with spiced pork and rice, are so traditional they are regarded as the national dish of Romania and are a favourite main dish.
Anyway, mamaliga (polenta) or any dish with pork meat is considered a national dish by any Romanian. There are jokes about the national Romanian vegetable, which is pork meat. Don’t argue with them and eat what they offer you!
Joking aside, it will be a nice and interesting experience to go to the international restaurant chains (McDonald’s, KFC) and see the differences in the menus as compared to your own country.
An interesting fact here is that Romanian McDonald’s offers a large variety of chicken based burgers, as the chicken is one of the latest replacement for the other Romanian “vegetable”, pork.
