The aim of this study is to evaluate the perspectives of consumers regarding the understanding of sustainable consumption in the fast food sector and to reveal the problems experienced by consumers during the consumption phase and the importance of the feedback on these problems, in terms of sustainable management. In a study in which 291 customers participated, data was gathered by providing the selected volunteering customers with a questionnaire. The SPSS 22.0 statistical package program was used to evaluate and analyse the data collected with the questionnaire. With this program the frequency distribution, rate, average and chi-square analyses were conducted. As a result, it is demonstrated that continuous studies should be conducted on the current and target customers in order to determine what the customer's feelings, thoughts and expectations are. Accordingly, product and service policies should be continuously guided.
