I went to a ramen place in Tokyo and to order ramen you had to insert money and place your order via this machine. This felt like going back to the early 90s but in a way that we are definitely not used to in western countries. It had a very retro futuristic vibe!
Was the machine just to order the food or did it cook it as well?
Typically these machines will give you a ticket, that you then hand to an employee.
