A lobby is a room in a building used for entry from the outside. Sometimes referred to as a foyer, reception area or entrance hall, it is often a large room or complex of rooms adjacent to the auditorium. It may be a repose area for spectators, especially used before performance and during intermissions, but also as a place of celebrations or festivities after performance. In other buildings, such as office buildings or condominiums, lobbies can function as gathering spaces between the entrance and elevators to other floors.
