Ah, where to get Eastern European food without spending all that money on airfare and hotels? Wouldn't it be great to have a listing of stores and restaurants that provide such tasty ethnic victuals?
Disclaimer: The following is not a commercial endorsement. I'm simply pointing out a few food sources that I know of.
Not far from Storvik, I've found the Kielbasa Factory in Rockville, Md. LOTS of varieties of frozen pierogies and other treats. Plenty of candy and canned goods imported from Poland. Some of these things are Polish specialties; others are simply food products you can get elsewhere, but with Polish-language labels. I think the people who run the store are natives of Poland, too.
Also in Rockville, plus two other sites in northern Virginia, is the Russian Gourmet. I haven't had a chance to check it out yet, but I hope to do so in the new year.
In my hometown of Gardner, Mass., Bonk's Market is still in business. I know, "Bonk's" isn't much of a Slavic name, but when I was growing up, it was the place to go for Lithuanian "white" (i.e., not smoked) kielbasa and fresh rye bread. (My hometown has even more French Canadian Americans than Polish Americans -- that's why Bonk's also serves up poutines rapées at this time of year.) I haven't been to Bonk's in years, but when I'm in Massachusetts next week, I'll have to check it out!
In the Boston area, the purveyor of Eastern European groceries seems to be the Baltic European Deli not far from Andrew Square. I've never been there, but maybe I ought to check it out on a future trip.
Finally, I stumbled upon PolishPlate.com, a Web site that lists lots of Polish shops and restaurants around the U.S. Of course I can't vouch for its completeness. Mostly, I'd like to hear from other Slavic Interest Group members, SCA folks, and re-enactors who can suggest food-related business they're familiar with.
