Rapid technological advancements have transformed people’s lifestyles and eating habits. While technological innovations have brought convenience, they have also contributed to the growing challenges of global warming and environmental pollution. This study aims to explore the perspectives of customers and Michelin inspectors on the service quality and sustainability practices of Michelin Green Star restaurants. Data were collected from the global Michelin Guide website and TripAdvisor, and text mining techniques were applied to analyze online reviews from both inspectors and customers. Using the BERTopic model, the study identified seven key aspects of restaurant service quality considered in Michelin restaurant evaluations, nine aspects specific to Green Star restaurant assessments, and eight aspects highlighted in customer reviews. These findings reveal the similarities and differences in the evaluation criteria used by inspectors and customers, providing valuable insights for restaurant operators.
