For real good home-style Jamaican cooking (fast), this rest stop is well worth the stop. Anything from Jerk Pork, Ackee & Salt Fish with roast breadfruit, or Manish water (aka goat-head soup), this will surely satisfy your cravings for authentic Jamaican cuisine.
If you're having any difficulty deciding which food stand to go to, try Cherry's One Stop.

Hidden Location: Close to the peak of Mt.Rosser on the Kingston/Ocho Rios route, you'll see a long row of restaurant stands which stretches about 300ft. You can't miss it.
