A block north from the train station on Straight Path Road, in a plaza, is a place called Island Jerk. The menu lists all the Jamaican standards. When I went, they had curry goat, oxtail, jerk chicken, escovitch fish, tripe and vegetables(!), rice and peas, etc.
It's pretty much take out only. I brought home curry goat and jerk chicken. Both excellent, if not quite as spicy as I like it. Very flavorful. The people behind the counter were very nice too.
Right across from the train station is also a place called "Pooh's Soul Food and Seafood", with a big sign for live crabs, and next door a Salvadorean place. Check it out next time.
