The BBC introduces viewers to a restaurant in Nuremburg, Germany in which you have no contact with a human being during your experience if you don't care to. Great quotes like "making the dining experience more efficient", and "you can relax while you wait for your food by sending email".

Basically the concept is a touchscreen menu, an magnetic card that manages your tab, a remote chef and a series of rails that wind through the restaurant and deliver food pods to your seat. It is a bit like the evolution of the sushi conveyor belt restaurant, but I think you generally still have to talk to a person in most sushi restaurants.
