I agree, I love everything down there too......but funny enough I don't eat fish, so I never order the ackee and saltfish meal.
But I love the rice and peas (beans) especially because they are cooked in coconut milk. I love 3 dives also but my favorite is probably the rice and peas at Pushcart because you can really taste the coconut milk, the rice just melts in your mouth.

I am not sure I have ever had a bad meal in Jamaica.....but I have had some that were over the top amazing!
