The purpose of this study is to provide implications by conducting research on the impact of ESG management activities of food service companies on brand image, lovemarks, and purchase intention to food service consumers. An online survey was conducted targeting food service consumers who used ESG management activities of food service companies. A total of 300 questionnaires were used for statical analysis by SPSS v.23 and AMOS v.23. The results of the study are as follows: First, The ESG management activities of food service companies were partially adopted as a result of not having a significant effect only on the environment (E). Second, As a result of the analysis of the moderating effect according to gender, in the case of men, the effect on brand image in the social (S) was more significant than that of women so it was partially adopted. These results seem to have considered the inconvenience of limiting the use of disposable products rather than environmental protection due to Corona 19. However, in the era of ESG management, food service companies will have to develop and implement active programs for the environment.
