Abstract

A drive-through window station of a restaurant has a food preparation area adjacent a food preparation viewing window. A driveway exterior the window positions a customer in a vehicle at an enhanced elevation whereby the customer may look inward and downward to view and direct the food selection, preparation and packaging by continuous communication using one or more spaced two-way speaker-microphones units. A canopy over the driveway enables proper lighting to view the interior food preparation. Sensor activated lighting increases the interior and/or exterior illumination when a vehicle enters the driveway, and decreases the interior and/or exterior illumination when a vehicle exits the driveway.
