"A lobby is a room in a building which is used for entry from the outside. Sometimes referred to as a foyer or an entrance hall.
Many office buildings, hotels and skyscrapers go to great lengths to decorate their lobbies to create the right impression.
Since the mid 1980s there has been a growing trend to think of lobbies as more than just ways to get from the door to the elevator, but instead as social spaces and places of commerce. Some research has even been done to develop scales to measure lobby atmosphere in order to improve hotel lobby design."
