Looking for Albanian/Bosnian/Serbian Grocery stores in the area
Well not near Silver Spring, but in Virginia near the Huntington Metro is the Balkan Grill, which I gather has a a small grocery next door with Bosnian specialities (http://www.balkangrill.us). The North Kings Highway Exit. This place got a lot of good press a couple of years ago. I have not been but thought it worth a mention.
There's a small place called "Euro Mart" hidden in a row of shops near the intersection of Rockville Pike and Route 28. They don't have a huge selection of items, but I believe the owners are a Bosnian couple and they are very friendly and helpful. They carry a selection of products from the former Yugoslavia and other European nations.
