Abstract: As a major source of food and plastic waste and a large consumer of water and energy, the hospitality sector is key to combating climate change. Sustainable practices in the hospitality sector optimize food production and use, introduce innovative solutions and increase employee satisfaction in running environmentally friendly restaurants. This study examines the changes required for a restaurant to make a sustainable transition and the role of key stakeholders (i.e., chefs, head sommeliers, owners and main suppliers) in this process. It focuses on a prestigious Slovenian restaurant that has been awarded a Michelin Green Star and is 80% self-sufficient. The single case study uses semi-structured interviews, the critical incident method and participant observation to collect data. The results showed that in the case of the analyzed restaurant, the lifestyle of the owner/chef decisively shapes the culture of the restaurant, laying the foundation for its sustainable transformation. The success of the transformation itself, however, depends significantly on the employees’ ability to learn and innovate and their active involvement in the change process itself, which impacts both day-to-day business processes and relationships between stakeholders. The latter is reflected in the role the restaurant plays in the local environment as a driver for sustainable community and sustainable entrepreneurship development.
