We offer our guests a customised catering experience that we tailor to each individual customer. With our customer relationship management, we build long-term customer relationships that are of great value to our company. We maintain a transparent communication culture throughout the GAMMA Group, both internally and externally.


Regionality and seasonal products are very important to the GAMMA Group and are a matter of course. The variety of products produced in Switzerland enables us to offer a seasonal and regional menu. For products from abroad, we pay attention to recognised and verified logos and give preference to products with the “Max Havelaar” label.


Ongoing investment in employees, machinery and vehicles sets the course for a profitable future for the GAMMA Group. Cost-efficient operations are the result of investments and innovations, which are the cornerstones of our strategy.


We keep up to date with new trends in process optimisation so that we can work cost-effectively. For us, detailed planning and a realistic budget are the key to success. The GAMMA Group is 100% self-financed. Sustainable growth is very important to us and is part of our responsibility as a company.


The GAMMA Group includes the companies GAMMACATERING, the event location Zunfthaus zur Saffran, the member restaurant HAUTE in Zurich and the Restaurant Theater Casino Zug. Joint synergies are utilised so that we can position ourselves as effectively as possible in the current market. All the companies are characterised by their individuality and uniqueness. But they all have one thing in common: a passion for hospitality!
