The store is in NE Minneapolis where there are a lot of folks with Central European origins, including Poland.
The Delicje cookies are also available in Hungary, but sold under a different name. The packaging is exactly the same, just a different word than Delicje, but now I can't remember what it was. Anyway, when I found these in Hungary, I felt like I had found an old friend.
This trip through the Polish grocery store cost me about 33 PLN. That will probably make my Polish friends gasp, but I think the price is well worth for a taste of Poland every once in awhile in Minnesota.
