This restaurant is a treasure. It's one of the last of a certain kind of Polish supper club that my grandparents loved back in the day.
Everything is cafeteria-style. The first time I ate here there was an hour and a half line almost out the door for dinner, but the second time I came close enough to closing time that there was no line at all. So come late for quick service.
Pirogues are enormous, al dente, and delicious. They're basically just huge ravioli filled with mashed potato and soaked in butter. Sauerkraut is actually sour and, big surprise, soaked in butter. Excellent. But the big item, if you ask me, is the stuffed cabbage (filled with meat and rice). No one knows how to do this dish right anymore spare a few grandmas, and their rendition is classic. I wouldn't change anything about it, including their homemade tomato sauce/gravy.
The big surprise was their 'house' brand grape soda, which we bought ironically and ended up greedily drinking.
