Super unique. Got very popular for its chicken-stock-baesd creamy soup that tastes fairly thick and yet very sophisticated. Makes you want to eat more till end. Tiny place and always a waiting line, but worth the wait, especially for the first time. There's a branch nearby in Ginza but don't go there because it's not as good. Stick to this place. One of the most impressed Ramens in my life when first had it.
