Kouya no Gourmet

Just as a gunfighter drifting through the dry wilderness stops by a bar to quench his thirst with a drink, Ryosuke Higashimori, a businessman, enjoys a small party after work at "Yoshino," an oasis he found in the wilds of Tokyo, where he tastes the owner's cooking, drinks, and converses with the owner and nameless regular customers.
