An inventor in Nuremberg, Germany has just opened a fully-automated restaurant, Baggers that delivers meals to diners via a gravity-powered rail system. No surly waiters or snobby sommelier, and you don't need to leave a tip for the machine. The kitchen is intalled directly beneath the roof of the multi-story restaurant. Customers order their meals using a touch-screen system that is placed at each table, and the entire restaurant is networked via a computer system. Customers' orders are registered upstairs in the kitchen and a computer in the cellar keeps track of supply stocks. The system also calculates the likely delivery times for drinks and meals at every table and keeps customers informed.
