Hakata Ramen is a Japanese ramen restaurant on the second floor in Nampo-dong, Busan. It serves ramen and tan tan men, and customers order and pay first, then take water, kimchi and danmuji themselves. The store is on the second floor, so customers walk up a narrow staircase, and the self-order system is a feature of the place. The ramen is hot, but the air conditioning is not turned on, so the store is warm.
