I've had Polish and Ukrainian food in NY and absolutely loved it, they had those huge fried meat dumplings that were great, I think the fact we washed it down with generous pitchers of Polish beer also helped. I've had a soup with bacon and other stuff and it was great too. It was in a sort of upmarket type of place though, defo pricey.
I really can't think of anything disgusting to be honest, I've eaten horse burgers, sausages and steak since I was very young, also had octopus in salads and stews, cuttle fish, calamari, fried cow brain, raw mince beef and all the other stuff we normally eat south of the Alps.
