Pelican bar hands down--you could do your own bar crawl-find some other people -find a charter taxi and set a rate and have him take you to all kind of local bars in Negril (west end and beyond) You could ask on this board for some suggestions for your do-it yourself bar crawl,am sure many would respond..
Pelican bar is just a unique, cool place-and it will get you out of Negril and a chance to see more of Jam....
