Kanda Matsuya isn't that Japanese gyuudon chain Matsuya but an old restaurant providing Tokyoites' flavor. Ikenami Shoutarou (池波正太郎), a novelist as well as a gourmet, also liked their foods. With an atmosphere of history, guided by a old & kind waitress, A-Mao sampled cold soba. It smelled mellow, its mouthfeel was exquisite, and the dipping sauce would bring you to the Edo period! After that, please do pour some cooking water out of the red pot into the sauce. Not to waste this delicacy.
