It's a fairly large place with the kitchen behind a wall so not visible. The "Train" is more like a monorail, with the guide way made of wood that goes around the counter and through the wall into the kitchen. There is an electronic beeper and a lighted push button is at each seat. There is also a touch screen display terminal at each seat for the customers to enter their orders. The orders arrive on a two car train of sorts. It's really two trays that ride on the wooden guide ways and are connected together. A total of 4 dishes of Sushi can be delivered with each trip. When your order arrives the push button flashes and the beeper sounds. When you have removed your order you press the button the send the train back to the kitchen.
This was a fun place and the Sushi was also quite good.
Here's a short YouTube video showing the delivery of an order. This was my first video with my new camera and I'm quite happy with the results but I just need to hold it more steady.
