A concession stand, or refreshment stand (American English, Canadian English), snack kiosk or snack bar (British English, Irish English) is a place where patrons can purchase snacks or food at a cinema, amusement park, zoo, aquarium, circus, fair, stadium, beach, swimming pool, concert, sporting event, or other entertainment venue. Some events or venues contract the right to sell food to third parties. Those contracts are often referred to as a concession, hence the name for a stand where food is sold. Usually prices for goods at concession stands are greater than elsewhere for the convenience of being close to an attraction and thus often contribute significant revenue to the venue operator (especially in the case of movie theaters). Additionally, outside food and drink is often prohibited to incentivise spending at the concession stands.
