A sandwich shop is a type of business that offers a variety of sandwiches, typically made with bread, meat, cheese, and vegetables. The two most common types of sandwich shops are diners and delis. Diners are usually casual restaurants that serve a variety of American-style dishes, including sandwiches. Delis are usually more specialized, offering a variety of cold cuts and other deli meats, as well as salads and other sides. Both diners and delis offer a wide selection of sandwiches, making them popular lunchtime destinations.
