Mystery Diner

The Mystery Diner service is a secret evaluation of the quality of the client’s product and service, carried out according to international standards within a given sector (for example, “Leading Hotels of the World”). This strategic tool aims to improve customer service and satisfaction. In some areas, this is still a little-known service, even though kitchen and hotel reality programmes have spread awareness of “mystery clients” who pretend to be guests while, following international guidelines, assigning scores to all aspects of service. At the end of our test, clients receive a general assessment of their restaurant or hotel that takes into account the experience of every purchase and service opportunity. This provides an ideal foundation for building an effective action plan that fills gaps and further strengthens winning aspects.
