Very cozy izakaya down in the basement on the main drag in Akakura Onsen town. I love squid ink pasta. When i heard this place served squid ink udon I knew I had to try it. Did not disappoint. The broth was jet black, thick and garlicky and the udon was nice and firm. The servings aren't the biggest so you need to have a side of tempura or something. Definitely use the bib provided as that stuff goes everywhere.
