This is the directoring debut for Jacques Besnard. The restaurant in the title is called Septime, named after the owner (Louis de Funes). A very two-sided person, smarmy towards the guest, but a hard and hysterical boss towards the employees. As the action takes place, Septime is welcoming a president (Folco Lulli) as a customer, a president (of which country we don't know) togther with his secretary Sophia (Maria-Rosa Rodriguez) and a security man. Suddenly during the dinner, fireworks goes on, and the lights go out. The result, a missing president.
Police chief (Bertrand Blier) takes over. There is no doubt in his mind, the president is abducted. Septime with the help of Sophia trying to solve the mystery.
Louis de Funes in topform and a very welcome to the always good Blier, so to speak the french version of Robert Morley.
As a French film from 1966 there's quite a lot of time with some carchases. Much of which happening around the ski resort of Val d'Isere.
A lot of good fun.
