Any good real good Jamaican food out here?

I recently moved out here from So Cali and I've been craving some real GOOD Jamaican food. I've seen a couple little places, but I've been told they're not good at all. I don't care whether it's a restaurant, or a hole in a wall type place, if they're good and has an A in they're window (maybe a B if they're absolutely worth it) then I don't care. Although I would really like to know of all places, but I really want the one that specialize in ox tails, jerk chicken and Jamaican patties. I'm in North LV (near the Cannery) but if they're not to far and is definitely worth it then that's fine with.

So in your opinion who's the best?
