Katsuura Tantanmen

Also known as "Katsu-tan", it is said to have been invented to warm up the cold bodies of fishermen and female divers. You will be shocked by the redness of the soup, which is based on soy sauce and contains plenty of chili oil, but you will become addicted to the exquisite spiciness, the sweetness of the onions, and the umami of the ground meat.
