These photos were taken in a bar somewhere in Brno, the Czech Republic. It might look like a nice decorative addition, but that train has a very specific purpose. Its rail passes through the bar, stops at customer tables, taking their orders. Then it goes back to the bartender, who sends the drinks in the train carts.
It’s a very ingenious system that spares the customers the trouble of having to tip the waitress. I wonder how quick it is though, do the customers have to wait a long time for the toy-train to bring them their drinks?
