Awesome ramen shop in the centre of town. Located in Tanukikoji 1 chome between Odori and Susukino. Get the special miso as it comes with a huge piece of charsui, grilled on one side. It is delicious!
Make sure to go early as stuff usually gets sold out by the early evening. I'd recommend going early lunch time. It's busy and you might have to wait a little while but it's worth it.
Address: South 2, West 1, Tanukikoji Arcade.
