Food with a halal logo should turn out as an advantage to premises that have proactively adapted to halal business ideas. As Islam teaches its followers on what food is good (halal) and bad (haram) for consumption, the attachment of Islamic decency and goodness to foodservice is expected to spur food premise Halal patronage. The objective of this paper was to investigate the role of religiosity as a mediator in the relationship between perceived behavioural control and intention on patronising at food premise with halal logo. Survey data were collected from supermarket shoppers in all four states in Malaysia such as Selangor, Johor, Kelantan and Pulau Pinang and analysed using partial leastsquares structural equations modelling (PLS-SEM) technique. The key findings were religiosity as an important part in an indirect positive relationship between perceived behavioural control and intention on patronising at food premise with halal logo, thus giving support to the mediating effect of religiosity. An explanation for this mediating effect was probably due to the high degree of dependency on religiosity among Muslim consumers.
