Try Mobay Proper. I've been there but it was during the day (a friend's cousin owns the place). From what he said, it's a hit on weekends and other nights. I got this from lonely Planet:

Lonely Planet review for Mobay Proper

Attracting a young local crowd, this exuberant bar serves libations on the terrace and has decent Jamaican cooking. Beneath a ‘chandelier’ of Heineken bottles, the pool table generates considerable heat, while dominoes are the rage with an older crowd out on the patio. On Friday night there’s a fish fry and vintage reggae, and live jazz rings in each new month on the first Sunday.
