I come from a Polish Family and although we are pretty Americanized, we do like the fresh Polish Sausage (not smoked like Ekrich or Scott Petersen) for holiday time. In the past few years we've had problems getting it or finding the sausage with the closest taste to homemade. We may have found it at this place, Joe and Franks.
Joe and Franks is a small deli in Bridgeview off of 87th and Ridgeland and very Polish. Not only do they have an extensive array of meats but they have other Polish delacacies too such as pierogis and globacki and if you look hard enough they do sell fresh chicken noodle soup and borscht (red and white). Among the other groceries they also have a good selection of imported Polish products such as chocolates and cookies.
So if you're looking for something homemade and fresh (sausage and sauerkraut rock!) check this place out...it was very crowded the day I went in there but it was well worth the wait!
