Abstract : The study was conducted at Restaurante Piscina-Ferroviário (a restaurant located in Nampula, Mozambique) in 2024. A mixed-methods approach was adopted, combining quantitative and qualitative techniques, including questionnaires administered to customers and interviews conducted with employees. The findings reveal that service quality dimensions such as cordiality, responsiveness, and service efficiency significantly influence customer satisfaction and intention to return. Additionally, challenges related to waiting time and lacks of service standardization were identified, which may affect service consistency. The study concludes that continuous improvement in service quality, combined with staff training and process organization, is a strategic factor for strengthening customer loyalty and ensuring the economic and social sustainability of organizations in the restaurant sector.
