ISO: Greek market in NoVA
Try Aphrodite at 5886 Leesburg Pike Route 7 around the corner from Mattress Discounter near Culmore Shopping Center. It has Greek as well as Middle Eastern Groceries. Also try Mount of Olives 3405 Payne at Bailey's Crossroads just a block East of Aphrodite. It is a Mediterranean Grocery store. Good Luck
There's an amazing Mediterranian/Middle Eastern Bakery and Grocery store off Duke Street in Alexandria. They carry Greek, Turkish, Lebanese and a whole host of other foods. They have wonderful pastries and breads and also have a good deli (their pizza is great and you can eat in).
From 395 you take Duke Street East (past Landmark Mall). Make a right on South Pickett street. There will be a strip mall on the left with a Home Depot. The Mediterranian Bakery is in the strip mall near the post office.
