Although it was not on the menu, I asked for a sake to go with the "beef tendon stew" (this restaurant's is a demi-glace-like Western style) and was served this one.
I had a drink at the Asahiya Sake Shop stand at Kitazawa Hachiman, which is famous (I think) for its fair stalls with reasonable prices.
It's so delicious.......
