This famed New York emporium operates in a historic Georgetown building that was once an open-air market. Though it is now closed in, this huge space still feels airy, with its high ceiling and windows on all sides. You’ll pay top prices, but the quality is impressive—charcuterie, fresh fish, produce, cheeses, prepared sandwiches and cold pasta salads, hot-ticket desserts like crème brûlée and tiramisu, and California wines. Also on sale are housewares; on-site is an espresso bar/cafe.
