There's a very unique restaurant in Tokyo where the entire service is automated. This high-tech dining spot doesn't have any servers at all. Instead, the food is put on conveyer belts so you can choose what you are interested in eating.
A tableside screen allows you to place special orders that arrive via the conveyer belt. Done eating? Slide your plates onto a small shute that calculates your bill. It's an amazing unique restaurant where the only humans at work are in the kitchen.
