My wife and I just moved into the Dunwoody area, so we checked out the E 48th Street Market. The food served through the restaurant was great -- fairly inexpensive and tasty. The house red wine was very good for being just a "house" wine.
More to the point, the grocery portion of the market is excellent. If you live in the area and want authentic Italian foods, oils, vinegar, salami, etc., then this is the place to go.
