Also, archaeologists used to find evidence of ancient restaurants. The buildings would open to the street and would have large kitchen areas in the back and service areas at the front. More amazing, however, is that these buildings wouldn't have any tables, chairs or space to sit down. The service areas are at the front of the restaurants and, clearly, people used to walk up to the service area, order their food, pay for it and go. Much like our fast food restaurants today.
