One thing I love about the city: juxtaposition. In our neighborhood in Boston's South End, these two shops prove the point. On the left, the new: Formaggio, an extremely upscale cheese and gourmet food shop. On the right, the old: The Syrian Grocery, a family-run business that, for more than 75 years, has stocked fresh and packaged food, spices, and kitchen tools for Middle Eastern cooking. I move easily between the two, as do many of my neighbors, and each shop contributes to the health of the other, though their styles and ambience are completely different. When we first moved into the South End 35 years ago, the space now inhabited by Formaggio used to be Tony's Produce, where the food was displayed in cardboard cartons, no prices were marked, and restaurants from all over the city would come to shop. I miss Tony's, which had been there nearly as long as The Syrian Grocery, but welcome the juxtaposition of the new.
