Fast food, German-style

Germany likes to call itself the "Land of Ideas" - and over the centuries it has certainly had plenty of them. It was Germans who invented the aspirin, the airship, the printing press and the diesel engine.

But Germany has surely never produced anything quite as weird as the automated restaurant.

I say "restaurant" - but it actually looks more like a rollercoaster, with long metal tracks criss-crossing the dining area.

The tracks run all the way from the kitchen, high up in the roof, down to the tables, twisting and turning as they go. And down the tracks - in little pots with wheels fixed to the bottom - speeds food.
