I have been into this store a few times now with my sister, and they have some pretty hard-to-find import foods. They also have a few different kinds of Polish beer, which aren't really bad if you're into that sort of thing.
The store is quiet, there's not really anyone else in there whenever I'm in there. It's a great place if you're looking for food that isn't easy to acquire here. They also have breads, fresh meat, and quite a few dozen variations of sauerkraut.
Also, like all Polish food stores they carry a LOT of pickled goods. This place is worth going to!
(I should also note, that Google Earth and Google Maps has this place listed in the WRONG location. It's just around the corner from Savers).
EDIT April 9, 2015: This place has recently closed. I believe the business was not thriving for the store in this area anymore. Such a shame, it was a rare find for this area.
