Try Shark's or Jamaica Style Restaurant on the West End for a chill, local vibe. Jamaica Style is across the street from Le Mirage and Sharks is across from Tensing Pen.
Your right on Mike, Sharks, next to Ahh Bees on the cliffs has some of the best food in all of Negril. I was blown away with the pan fried snapper. And you just GOTTA LOVE the real Jamaican vibe. It's awesome.....can't wait to get back there and places like it.
