There used to be a restaurant (well, Hamburger Joint) in Van Nuys, CA - it was called the Van Nuys Choo-Choo - nothing like the bar in Prague, but hamburgers, fries, hot dogs and the like - used modified O-Gauge Lionel stuff to carry the food and drinks (Modified Flat cars and Gondolas) It had two main lines on the main counter, - manually controlled with color-coded on-off switches to stop the train in the appropriate place. Nothing as elaborate as the Czech one, It also had two more tracks up near the ceiling running around the place. Closed in the 60's - a pity.
