While the importance and prevalence of digitalization are constantly growing in many sectors, the hospitality, gastronomy and tourism industries have been severely tested worldwide in the last two years. This review aims to identify the most frequently discussed topics linked to Hospitality, Gastronomy, Tourism and digitalization. It also highlights other emerging trends in these sectors over a specific period. The paper is based on fifty high-quality, up-to-date academic publications' content analysis from Web of Science and Scopus databases. Among the most discussed topics in the field are virtual and augmented reality (VR and AR), contactless guest experience, chatbots and artificial intelligence (AI), location-based services, and the Internet of Things (IoT), which uses internet connectivity for most activities. Given the industry's highly competitive nature, digitalization can lower the costs of running a hotel, gastronomy or tourism business. By digitalization of chosen time-consuming processes, if implemented correctly, the number of workers needed can be reduced. These processes can also help with quality and highly effective staff training. However, the research also shows that the human aspect of work will likely be irreplaceable in these fields and always needed. This paper contributes to understanding digitalization and emerging trends in the hospitality, gastronomy and tourism context. This study also provides valuable resources for current researchers in the field and those entering this area of research. Further, it helps the practitioners to track the current opportunities in the field.
