Very simple place, run by two great guys - a father and a son. The food is good, not very refined but comfort food. The experience is just amazing. We were wandering around Duluth, searching for an authentic experience, and we entered this little place that looked like nothing, and didn't even exist on Yelp, and then we found it. The guys told us stories about their homeland, explained to us how the food is made (try it at home), and at the end the father played Hungarian dances for us on his violin. My wife almost broke in tears when he played her favourite song - it was that much of an experience.

I met the son in Patati Patata last week and he recognized me. They seem to be genuinely interested in their clients. That personal attention you get from them is not fake.
