Through the ordinary small events of his professional and personal life, a forty-year-old man lets himself go on impromptu escapades at random along the paths that the big city offers. This vagrant impulse soon takes on the appearance of a sentimental journey, punctuated by images of the walker's youth.

This manga simply describes how Gorou Inogashira, the main character, chooses and takes a meal. Unlike other gourmet manga, Gorou likes to eat at cheap restaurants and no trivia on cuisine is given. The authors are trying to depict the essentials of the act of "eating" by Gorou's monologue, which comprises most of the lines of this manga.
