I have no idea what authentic Caribbean food is so I'll try to explain what I tasted and you can go from there.
I ordered a homemade ginger beer to go with my water and I have to say it was the best ginger beer I've ever tasted. It wasn't nearly as carbonated as the ones you'd buy in the bottle such as Reeds and was a little sweeter. The ginger was so intense that by the end of the glass I was sweating a little from the spiciness. It was REALLY good and anyone who enjoys the mild tingle of ginger ale should try it at least once.
As an appetizer I had the fried ripe plantains. They came out golden brown and had a kind of soggy consistency. In my head I was thinking of a crisper appetizer but I thought they were delicious. I'm not sure how they are prepared traditionally. The inside was sweet and a bit tangy and surprisingly was not as similar to a banana as I thought it would be. I really liked them and was impressed at their ability to walk the fence between sweet and savory.
I ordered the jerk chicken as my entree and thought it was awesome. The spiciness keeps pace with you as you eat it. It doesn't overwhelm you right off the bat but by the end of your meal you usually are ready to succumb to its spice. The chicken came bone-in which in my opinion is always a good sign. I hate it when people sacrifice flavor for convenience. The sauce around the chicken was abundant and delicious and the jerk rub was proportioned perfectly for me. I had a sign of "rice and peas" which was more like rice and beans, as well as black beans. The rice was fluffy and abundant and the black beans were really good.
For dessert I had the Jamaican rum cake. It came with a small scoop of ice cream and a decorative fanned out piece of soft, sweet mango. I did not care for the rum cake because, once again, being unfamiliar with Caribbean food I was expecting something else. The cake was incredibly dense, moist and seemed to be full of molasses. I am not a huge fan of molasses so I did not care for it as much.
All in all the food here was incredible. The waitress was really nice and kept our drinks filled. No one was in the restaurant as is the usual situation with non-chain restaurants in Pittsburgh so don't let the lack of customers deter you.
