Pressa's and 3 Dives are both within walking distance and great places to eat with a real Jamaican feel. Although I have never seen sunset from Xtabi, I know it is fantastic from Blue Cave Castle which is close by, so Xtabi must be good too.
Take a day trip to Mayfield Falls. Everyone will love it and the more the merrier. We just combined a trip to Mayfield Falls with Roaring River for a full day of fun.
