Solitary Gourmet (2012) : 5x8

Inogashira Goro (Matsushige Yutaka) visits a client in Yoyogi-Uehara referred to him by his associate Takiyama. The client who owns a sign shop is not at home so Goro meets with the wife instead (Yokoyama Megumi). Alone with the wife, Goro looks at her eyes and senses a strange atmosphere. Unnerved, he hurries up and finishes the meeting and leaves. Before he goes, the wife hands him a letter in a pink envelope. Fearing that it is a love letter, Goro nervously opens the envelope and reads it... Later, in a foul mood, Goro goes in search of another client, a tatami shop owned by Ozaki (Ishii Kenichi) who was looking for a foreign-made bike. After the meeting, the smell of dried rush used for the tatami relaxes him and soon, he feels hungry. He walks down a narrow alley and finds a shop with dried chilies in front. At the entrance, the signboard says "Gatemo Tabun, Bhutanese cuisine". Without any idea what kind of dishes are being served, Goro takes a plunge and goes inside...
