Negril, and Jamaica as a whole, is great for fresh and delicious seafood, as well as its main staple, jerk seasoning (a pepper and allspice-based concoction), which is largely used on chicken. This is not to say that there aren't other things to eat in Negril than lobster and jerk chicken; the small city caters to Western tourism and has all of the standards of the Western world in multitudes.
One particular phenomenon found in Negril (and in other resort towns) is that of the beach vendor. They can be found up and down the lengthy stretch of beach, selling freshly cooked lobster or jerk chicken. You can also get fresh coconut juice anywhere, although we suggest you crack your own coconut for a drink.
As far as popular places to eat, there are those that are popular because they are touristy and those that are far more authentic. We'll list them both, because you'll find that they often overlap in such a small destination; you'll also find that most places you come across will have their own jerk chicken recipe. Although by no means a comprehensive list, some of the best restaurants in town where you can get jerk chicken or pork on the cheap include Three Dives Restaurant (near the Ixtabi Resort), Bourbon Bar (great live reggae), and Ossie's Jerk Center (across from the Palms). There are also plenty of classy restaurants with great ocean views. Rick's Cafe is the go to for the sunset and your fair share of cliff diving with dinner, while the Rockhouse Restaurant incorporates the nearby cliffs into the landscape design, making for an attractive dining environment. Norma's provides Jamaican fusion on the beach, while there are plenty of other resort restaurants that are par for the fine dining course. Then again, there is the intrigue of the simple shack where a local cook throws seafood on the grill straight from a cage anchored in the surf; nothing is fresher. Places like The Office of Nature in Bloody Bay do it this way, but the locals will tell you a “proper” restaurant like Sweet Spice will have the best lobster and its just as cheap.
Don't deny yourself the seafood or the jerk experience while in Negril; where to go? That's totally up to you. Do yourself the favor of browsing our restaurant listings and go from there.
