A delicatessen, often shortened to "deli," is a retail store that specializes in selling fine, unusual, or foreign prepared foods. These establishments typically offer a variety of meats, cheeses, and sandwiches, along with salads, pickles, and other gourmet items. Delis may also sell specialty grocery items, such as olive oils, spices, and breads. Delicatessens originated in Europe and have become popular in many countries, especially in the United States. They often serve as a gathering place for people to enjoy a quick meal or snack. Many delis also provide catering services for events, offering platters of their popular items for larger gatherings.
