My mouth literally watered when I typed "Jamerica" in the search bar to write this review. So we'll start with that.
I ordered the jerk chicken with rice and beans at the Willy Street Fair this past summer and it was one of the most delicious things I have ever had. It tasted so wonderful and it was cooked perfectly and I crave it all the time now.
I've never actually eaten inside the restaurant so I don't have any thoughts on that, but the food speaks for itself. Try it. You will not be disappointed!
