Inogashira Goro (Matsushige Yutaka) was in Setagaya waiting at a tennis court for a client (Owada Baku) to finish playing a match with friends. Much to his chagrin, Goro who is not much into ball-based sports, obliged the client's request to practice swinging the racket... After their meeting, Goro managed to follow a somewhat vaguely drawn map towards Kyodo station. He felt hungry after experiencing relief from reaching the endpoint of the map. However, he was at a residential area with no shop within sight. By chance, he saw a sign outside a usual looking detached house. It read "Macina Mecina", a shop that offers buffet meals. Out of his "hunger's curiosity", he entered and got ushered in by the proprietress (Ishino Yoko). Goro began to enjoy the real pleasure of a buffet feast, determined to go over and taste each and every dish...
井之頭五郎(松重豊)は、仲間テニスを楽しむ中西哲夫（大和田獏）をコートで待っていた。このあと商談するためだ。試合を終えた中西は、球技が苦手な五郎に「やらず嫌いはもったいない」とテニスを勧められて素振りをしてた五郎。急にエア・ケイを振られるが解らずその場を盛り下げてしまう事態に…。
商談後、五郎は中西に最寄り駅の経堂までの地図を書いてもらうが、どうにもわかりづらい。ようやく目印の坂を見つけた五郎は、安心したせいか急に空腹を感じる。しかしここは住宅街。店を見つけるのを諦めようとしたその時、一軒家にしか見えない店（マッシーナメッシーナ）を偶然発見する。しかもメニューはバイキング一択！

女将（いしのようこ）が丁寧に作ったメニューを自由に選び満足度200％の一人バイキングを堪能する。
고객 상담을 마친 고로는 가장 가까운 역이 어디인지 묻는다. 고객이 역까지 가는 길을 약도로 그려주었으나 알아보기 어려워 난관에 처한 고로. 때마침 약도에 쓰인 언덕을 찾은 고로는 안심해서인지 공복을 느끼며 식당을 찾다가, 도무지 단독주택으로밖에 보이지 않는 뷔페집을 우연히 발견하게 되는데...
