“I would without a doubt recommend Gast is Koning to companies that not only want to improve their hospitality, but also want to create a culture where hospitality is the main focus. From the very first moment it was clear that Gast is Koning is more than just a Mystery Shopping company. The team behind Gast is Koning radiates enthusiasm and passion and they are committed to building a hospitable culture within teams. What I really appreciate about Gast is Koning is that the team looks beyond the standard solutions and they are truly committed to the success of their clients. This has resulted in concrete improvements in the hospitality within our organization.”
