Restaurants providing halal (permissible according to Islamic jurisprudence) food are important to Muslims. However, many factors influence customers' intention to patronise halal restaurants. This study examines the antecedents of patronage of halal restaurants. The study questions whether there is an effect of perceived value, perceived usefulness and culture on the intention to patronise halal restaurants and whether religiosity moderates the relationship among these variables. The purpose of this study is to explore the factors that influence Muslim customers' intention to patronise halal restaurants. The study specifically investigates the relationships among perceived value, perceived usefulness, culture, religiosity and intention to patronise halal restaurants. The study is based on a sample of 323 halal restaurant consumers. The questionnaire measures the following variables: perceived value, perceived usefulness, vertical collectivism, horizontal collectivism, vertical individualism, horizontal individualism, religiosity and intention to patronise halal restaurants. The study shows that both perceived value and perceived usefulness have a direct influence on behavioural intention to patronise halal restaurants. In regards to the effect of collectivism and individualism, only horizontal collectivism and vertical individualism have a direct influence on purchase intention. The current study also finds that religiosity moderates the relationship among perceived value, perceived usefulness, horizontal collectivism and horizontal individualism with respect to behavioural intention. The study shows that the Muslim intention to patronise halal restaurants is influenced by the perceived value, perceived usefulness of halal restaurants and culture which is also moderated by the Muslim level of religiosity.
