Get the jerk pork. I bought a half a pound last time I went. Place is a dive. But the jerk pork is excellent. If you want sauce - get it on the side. And if you like it hot - ask for hot sauce on the side. I just get it to go in the summer. Get a drink and walk and eat. Or buy it and ride/drive to the beach and dig in.
Or I would just get some oxtail. Don't forget the hot sauce. The oxtail is a little fatty and gelatinous but this is the one time I don't care because it's so tasty. I would just get some hardo bread with it. Hardo bread is an acquired taste. I love it having grown up with it. I would get some plaintain only if it's fresh. Dumpling only if it's fresh and hot.
I never tried their soup or their curry roti, nor their fish, but it's on my list. I would only get their fish if they make it to order fresh.
I know my Jamaican food, having eaten almost everywhere excellent in Jamaica. The food in Jamaica is one of the best in the world - as far as vacations go - especially if you like it hot.
Hit UP Mr. Jerk in the summertime!
