It's difficult not to salivate when walking into D'Agostino's on Waterfield Street in Winchester. As soon as the doors open, the aroma of fresh deli eats fills the air. This deli carries Boar's Head meats and cheeses and can cater any event. D'Agostino's also carries a variety of grocery items, such as potato salad, deli rolls, potato chips and more, good for those summer barbecues.
