if you want to do something really cool, and have a traditional old time style cooking dinner with everything and hard food plus more, check in with miss sonia.
she's been cooking out of her granny's recipes for decades, used to carry her son and fruit into negril every day from years gone by all the way from grange hill, then took to starting a fire on the beach and cooking up a few pots and then everything from there.
work out a menu, a price, with her and set her up with a deposit, set the date and come back and eat like kings. i don't normally eat sea bugs, but I'll put down a plate of her curried lobster no second thoughts.
lots of worthy mentions to hit up, negril is a chowhound's wet dream.
local food sweetspot i see was mentioned- also a nod must go to the king of box food one mile.
bourbon beach has one of negril's only and true jerk chicken pits. sadly, they ditched the potato press for frozen. used to be you could ask, but I haven't seen the press around at all.
barrel chicken is step-a-side, pretty much hands down- and you can tell that because he's always out first.
be on the lookout for vision, a street cart with amazing soups and other foods. another food vendor on the street worth checking into is priest ellis, ital, and there is another negril standby out a lot also doing ital, fix up a nice full plate for you on the serious cheap.
kuyaba has been mentioned, another romantic spot with real pizza (and real furniture) is sunrise club, also the best espresso in negril.
italian cafe is another good pizza joint, although I make them double up the dough.
i'll second and third ossie's,and sweet spice, and if you want an undiscovered sweet spice stroll into juicy j- don't be bashful try the juices for which the place is named for. ask for the ones made in house.
miss sonia also makes patties, hand made, and taught niah, who also has a devoted following.
i had a few nice dinners at the Palms, especially on Sunday for the live Jazz.
you'd need a three week stay to hit every place worth it.
