My wife's family is polish and when we go to Sokolowski's I like it, but she is in heaven.
The stuffed cabbage (halupki) and the pierogi are standard and she has been surprised by a few unusual dishes from time to time.
Absolutely authentic polish food, made from scratch just the way she remembers he mom cooking it.
The place isn't fancy and the servers won't hover over you (it's a cafeteria afterall). It's not a place to go if you're watching your diet, as ethnic food is generally full of carbs and fat, but if you want a delicious meal and a fair price, this is your place.
