This place is a little difficult to find, being tucked away and sharing space with another restaurant. But its well worth the time and money if you need a pierogi fix.
They serve a pretty wide range of pierogis and other things to spice up the flavor. I had the pierogis served with duck. The duck was tasty and crispy and the pierogis were just OK.
My main complaints about the pierogis here are founded in their cooking style and how doughy they feel. They have 2 options for cooking your pierogis: boiled or deep fried. The traditional way I have seen it was boiled and lightly fried in butter. The solely boiled method just felt unfinished to me. Maybe because I was expecting it to be cooked in the more traditional sense, it seemed to be a bit heavy on the dough side.
And lastly, the beer selection is pretty limited, but at least its fairly cheap ($5-6/glass).
