This paper reviewed the relationship between job satisfaction and service quality, and the moderating effect of gender in restaurant employee. Based on the responses from 288 employees, the results of multiple regression analysis showed that intrinsic job satisfaction(JS) and extrinsic job satisfaction effect positively on all service quality factors(tangibles, reliability, responsiveness, empathy). The results of moderating analysis showed that intrinsic JS effects positively on all service quality factors irrespective of gender, but the positive effect of extrinsic JS on tangibles and empathy is more positive in female than in male employee.
