"Hailed as the place to party on Montego Bay’s “Hip Strip” Gloucester Avenue, Margaritaville is perfect for anyone looking for exciting entertainment, a lively atmosphere and delicious food. Opened in January 1996 by Jamaican owners Brian Jardim and Ian Dear to appeal to both visitors and the demanding local clientele, Margaritaville has established itself as a ‘must see’ for both. The busy open-air bar downstairs serves up a rainbow of tropically-flavoured margaritas and 22-ounce bongs of beer. Blended fruit punch with or without some Appleton rum is simply delicious. And the kid’s menu is sure to satisfy even the pickiest half-pint! " (sited from the  Margaritaville website)  Check out the website, there is a lot of great information about the place.

Other places for night life in Mo Bay are Pier One, which is a restaurant/bar right on the water downtown and is cab ride from most hotels.  Friday night is the best night to go and there is a good mix of tourists and locals with some good reggae/reggaeton dance music playing.  Other places to consider are the blues/jazz club right next door to Margaritaville. 

If you wish head out of Montego Bay to Sandy bay for a country dance at Uprising bar and night club. You may see a bit of strip show , but it is a very cool place.
