Abstract In this study Customers’ expectations factors in restaurants by Domingo Ribeiro Soriano, The attributes which influence Spanish customers’ decisions to return to a restaurant for another meal were examined. The survey reported on by the customers in this study used a quality rating on a Likert scale from 0 to 10. The results show that quality of food was rated as the most important attribute, followed by quality of service, cost/value of the meal, and place/ambience of the restaurant. Male customers did not rate the attributes any differently than female customers. Introduction The Spanish restaurant sector was selected for this study because, in the last three decades, the restaurant sector as a percentage of Spain’s total economy has been consistently growing. Tourism is one of the most important sectors of Spain’s economy and the restaurant sector is strongly influenced by developments in tourism as well as by other factors such as demography, lifestyle, national or regional customs and, the country’s economic situation. In Spain there is a general tendency towards people eating outside of the home, and eating out is viewed as being part of the lifestyle. Knowing what the customers want and what makes them come back is important for the restaurant sector, therefore the purpose of the research was to examine the customers’ expectations and those factors that influence their decisions to return to a restaurant for another meal.
