Reflexive Consumption refers to decisions made by individuals in line with their previous knowledge and experience, whether influenced by the environment or independent of the environment. This study aims to determine whether consumers' reflexive consumption decisions in food and beverage businesses differ according to demographic variables such as gender and age, and to determine the relationship between reflexive consumption and consumption frequency in food and beverage businesses. For this purpose, Social Identity Theory and Contact Hypothesis were used in explaining the research hypotheses. A quantitative design was followed within the scope of the research. The sample of the research was customers of restaurants providing food and beverage services in Istanbul. Data obtained from 388 participants within the scope of the research were analyzed in the SPSS program. As a result of the research, it was determined that demographic characteristics did not create a difference in reflexive consumption and that consumption frequency in restaurants was not related to reflexive consumption. As a result of the research, suggestions were presented to restaurant business managers on how to provide customer satisfaction in the context of reflexive consumption.
