A drive-in is a facility (such as a restaurant or movie theater) where one can drive in with an automobile for service. At a drive-in restaurant, for example, customers park their vehicles and are usually served by staff who walk or rollerskate out to take orders and return with food, encouraging diners to remain parked while they eat. Drive-in theaters have a large screen and a car parking area for film-goers.Carhops serving at drive-in diners

It is usually distinguished from a drive-through, in which drivers line up to make an order at a microphone set up at window height, and then drive to a window where they pay and receive their food. The drivers then take their meals elsewhere to eat.

The first drive-in restaurant was Kirby’s Pig Stand, which opened in Dallas, Texas, in 1921. In North America, drive-in facilities of all types have become less popular since their heyday in the 1950s and 1960s, with drive-throughs rising to prominence since the 1970s and 1980s.

The largest Drive-In still in operation is The Varsity of Atlanta, Georgia.
