Here you can see one of the jerk chicken stands I told about you before. The chicken is cooked in the oven on the right of the image. I do not remember the name of the lady in the picture, but she was very friendly, and her jerk chicken was the best I tried in Jamaica.
If you buy a chicken you can choose which sauce you want with it. There is the spicy one and ketchup. The chicken is accompanied with rice and beans. You can buy a drink in stands like these. Other stands sell beers, tobacco, breads and others.
