I have to agree that American, English and Australians can be the type where all they eat is burgers, chips, coke and pizza, but why would you want to marry a guy like that???
Surely there are plenty of guys on here, like myself who would jump at the chance to eat Russian/Ukrainian food.
I was married to a Tibetan lady for twenty years and I loved her to cook Tibetan food, but it could not be eaten frequently because Tibetan food is usually always meat meat meat and these days a lot of us want healthier food with lots of vegetables.
It will depend on the man for sure, but again I say, a man who does not appreciate the dishes from your culture is perhaps not the right sort of man. Think about it.
