This trifecta of to-go eating starts with one of Ina Garten's favorites: the cheese shop. Here you'll find an enticing array of cheeses from all over the world, as well as baguettes and crackers for pairing. In addition, the Cavaniola family owns Kitchen, with foods and baked goods for takeaway, as well as a wine shop housed in the historic Umbrella House, which housed troops during the Revolutionary War.
Round out your menu further with a stop at The Seafood Shop (356 Montauk Highway, Wainscott, N.Y.) for fresh seafood salads and ready-to-eat meals.
