How does an, Michelin Star, inspector actually inspect an establishment?

There are three kinds of inspection.

Test Meals: the inspector dines anonymously in an independent restaurant or a hotel restaurant

Full Overnight inspections: an anonymous overnight stay in a hotel Inspection visit: The inspector introduces himself or herself and visits the whole of the establishment with the manager to evaluate the installation of the establishment and see how it works from behind the scenes; he or she will also evaluate any new developments/improvements in the establishment. The inspection visit is the only way to see an establishment from every angle and as such is vital to the inspection process and to the information we supply to our readers. An inspection visit may follow on from a Test Meal or a Full Overnight inspection, but in these cases the inspection only takes place after the bill has been paid. In any case, once the inspection visit has been completed, that particular inspector will not return to the establishment for several years. This guarantees complete anonymity for the next visit

The report: After each of these visits, and on the same day, the inspector compiles a full report on each hotel or restaurant, according to a precise and well-established method.
