The owner of TOYOJIRO, a highly-rated Jiro-style ramen restaurant in Kyoto, Japan, took to Instagram to declare war — threatening the duo, who slapped his eatery with an awful one-star review.

Kyoto is not all traditional cuisine. It has become one of Japan's leading ramen hubs thanks to being a student town. Tastes evolve and flavors change as restaurants strive to satisfy clientele.

Invert these ideas, and you basically get Kyoto Station ... lie more than 50 restaurants, nine of which are ramen shops. They live on the 10th floor, along Ramen Koji, or Ramen Alley.
