For our evening meal in Fukuoka, several in our group chose to go to the 5th floor of a mall where all the restaurants there focused on different ramen specialities. This would not be your cheap college meal.
In front of the particular restaurant we choose, each person tapped the screen to select their desired ramen dish and inserted the correct amount of yen. Ticket receipt in hand, we gave the receipt to the waiter. I would have to say, it was quite tasty!
