I've been here a few times and had the jerk chicken, which is good. Today though I had a jerk chicken roti, and my friend had the callaloo and chicken. Both meals were delicious, and my roti was actually a little too big for me (and I have a very healthy appetite).
The atmosphere is VERY basic, and the service is very casual, but friendly. You can tell that Carribean Bistro is totally family run. I asked if they had any summery drinks, and the server offered me something (sorry I didn't catch the name) which was fruity but had a hint of ginger in it. Very good. We were never given a bill, and our dishes were never cleared from our table, but we didn't mind, because you just know going in that everything is going to be very casual. Plus we were so satisfied from the food that it was hard to be unhappy.
Our meals, with a drink each (no alcohol) came to $30 + tip.
