I tried this place after seeing them on here, and have ordered from them several times since on Gowaiter. Their food is delicious, and with their "Green zone" menu, they offer a bunch of vegan options. The food is very tasty, and 100% authentic Jamaican. The problem is that the prices are fairly moderate - $12-15 a dish on average for an entree, and ~$7 for appetizers - with portions that don't blow your mind. A couple dishes I've ordered I've definitely felt disappointed with the price to portion ratio.
Overall, though, I'd recommend paying them a visit. The food is delicious, they cater very well to veg*ns, and the waitstaff are all very pleasant.
Cons: Somewhat $$, Portions smaller than you'd expect
