There is a small French restaurant called Bistro Pas Mal which sells exquisite food and its own mulled wine in a nook of a working class neighbourhood in Tokyo. Its chef Mifune Shinobu trained at French-style inns and restaurants in the countryside of France for more than 10 years but has completely no interest in Michelin stars, status or titles. He has an outstanding memory of the flavours, colours and scents of ingredients and people’s faces, and also notices the smallest details. Despite Mifune’s taciturn, inscrutable nature and artisan spirit, he cares about people and wants to heal them with his food. However, his kind intentions can easily become meddlesome. Takatsuki Tomoyuki becomes a waiter at Bistro Pas Mal after a strange turn of events. But not long after he begins working there, he feels bewildered by the stream of troublesome customers coming to the restaurant such as the fussy Kasuya Koichi who makes special requests as well as Tsuruoka Tadashi who gets into an argument with Kawade Keiko, a woman that seems to be his girlfriend, and ends up finding fault with the dessert. Mifune helps unravel the problems or worries of these customers with his extraordinary powers of observation and deduction.
