Goro has been busy lately. Although he is thankful for the work, he has been feeling a bit tired. He goes to Sakuragaoka via Chitose-Funabashi Station to visit the younger sister of a friend. She is yoga instructor, Saito Rei (Asami Reina), who wants to consult Goro regarding changing the interiors of her own new yoga studio where she is planning to move into soon. She also taught Goro a yoga technique that could help him relax in case he is feeling tired. After the meeting, Goro tries the yoga technique in the middle of the street to see if it works. However, he feels hunger instead of relaxation, and so he goes in search of an eatery. While walking in a residential area, on his way back to the station, he comes upon a small sliver-type of building, which has two entrances. It is a yakiniku shop and bar, called "Maasan", that serves "Jingisukan (Genghis Khan)", or grilling of lamb meat and mutton. Goro enters inside and is greeted by the owner (Kawano Naoki). He takes a seat by the counter, next to a customer, an old man and a regular of the shop named Yoshida (Mickey Curtis). Goro notices that the shop offers varied ways of cooking sheep: grilled lamb chop, sheep rump, offal, neck meat, sheep fat, mutton soup, and even cheese made from sheep's milk. "This shop's sheep level is high," Goro says later on...
井之頭五郎は最近忙しい。忙しいのは有難いもののちょっと疲れを感じていた。
「なんかパワー系なもの、入れたいなあ…」そんなことを思いながら、知り合いの妹、ヨガインストラクター・斎藤玲(浅見れいな)のいる文化教室へ。今度初めて持つ自分のヨガスタジオの内装を五郎に頼みたいという。嬉しそうな玲を祝福する五郎だった。
帰り際、疲れが取れるポーズを教えられた。帰り道でひっそりやってみると、腹が減った。住宅街を歩いていてジンギスカンの看板を見つける。三角形に近い建物は二方向に入り口がある。「なんか凄いつくりだな…」
店に入り、店長(川野直輝)に案内されカウンター席に座ると、そこには独りでジンギスカンをしている常連たちがいた。常連の吉田(ミッキー・カーチス)の前に「羊のペコリーノチーズ」なるものが登場。吉田は「これ以上、ワインに合うツマミはないね」と、ワイン片手にジンギスカン鍋でそれを焼いている。
五郎はおすすめAセットとせせり、ライスの並、ウーロン茶を頼む。ロースと玉ねぎはタレ、ランプはクミン塩で食べるよう店長に勧められてやってみると、とにかく旨い。止まらなくなった五郎は、ラムチョップと旨口くちロースタレ、羊の薬膳スープ、それにご飯のお替りも頼んでしまう。ラムチョップをいつまでもしゃぶり尽くし、大満足。疲れを忘れた五郎だった。
