A ramen restaurant’s entrance may look similar to other restaurant. At the entrance we have a machine that we choose the type of Ramen we want to eat and add toppings or some other side dishes.
Payment on the machine will get some tickets. We sat at a table or at the counter and give these tickets to the person who attends us, and within minutes they bring order. Depending on the restaurant, even the same cooks prepare and collect the ticket order.
This system is meant to serve customers faster, and how to get paid when we just can go directly without waiting for us to charge.
