At Matsuba's Nishin-Soba main store in Kyoto. It is said to be Matsuba's original dish that goes well with soba. It was so twisted that I couldn't taste it.
Hmmm, I see. This is good.
It has a sour taste, but it is well balanced with sweetness.
I wondered what it would be like, but it's as good as I expected 👏.
