This research examines the interrelationships among the scope of tourism, travellers’ food choices, and the restaurant business in European capitals. It employs a sustainable and electronic tool, Octoparse 8, to gather and analyse a substantial volume of data. The study utilises computerised data including a total of 10 million reviews pertaining to 21,885 eateries located in 27 European cities. The findings of the research indicate that a significant majority of travellers exhibit a preference for dining establishments that provide vegetarian-friendly and vegan alternatives, as well as gluten-free choices. Furthermore, these individuals tend to gravitate towards European and Mediterranean cuisine when selecting restaurants. There are a limited number of capital cities, like Madrid, Paris, and Rome, where visitors tend to choose local cuisine due to the renowned reputation and longstanding culinary traditions associated with these respective nations. When evaluating a restaurant, visitors do not rely on pricing as a determining factor. Additionally, when discussing captivating scenarios, it is important to examine the cities of Roma and Valetta.
