Nearby spots: Alfreds is decent for lunch. Known for their fish and chips. Sweet Spot is a good cheap spot nearby also. It's a cook shop style place with standard Jamaican fare such as curried chicken, brown stewed chicken, oxtail, curry goat, etc.... A little more upscale and still in walking distance is the Italian Cafe. Kuyaba is beachside and nice spot for upscale dinner. It's about 1/3 mile from Rondel.
If you're willing to take a cab to the west end I consider Ivan's at Catcha Falling Star to be one of the best ocean view restaurants in Negril. It's a good place to go for a sunset and upscale dinner. More modest with an ocean view is Swordfish. Tensing Pen and Rockhouse are both upscale and on the same level as Ivan's. Downtown Sweet Spice is a good spot for a sit down casual dinner.
