Assessment of Spatial Factors Influencing User Satisfaction in Quick-Casual Restaurants

ABSTRACT Users' evaluations of the restaurant environment are influenced by various design factors and their level of satisfaction and comfort, of which colour is an essential component. Several studies in the literature have demonstrated the influence of colour in interior design on human behaviour and psychology in various contexts. This study investigates the spatial factors influencing users' satisfaction in quick-casual restaurants. User satisfaction was measured using four major elements: product, service, price, and physical environment. This study used a questionnaire to assess user satisfaction in four quick-casual restaurants in Ankara, Turkey. The emphasis on colour effects was intended to evaluate the physical environment of the restaurants. The study results, which included the participation of 120 restaurant users, show that participants rated the various restaurant environments in a variety of ways. The assessments provided by the participants are statistically tested for significant differences based on gender, frequency of restaurant usage, and colour properties for both user satisfaction and the evaluation of the physical environment using one-way between groups of variance (ANOVA) (p < 0.05). The findings show that demographics have a limited influence on restaurant user satisfaction, though it varies depending on colour properties. Additionally, the results suggest that the environmental colours of quick-casual restaurants significantly influence user satisfaction, overall satisfaction levels, and the evaluation of the physical environments.
