For Breakfast on the beach we love Alfreds, One Mile Cook shop by Momma Flo's is also another great place for breakfast, and also Pilot Cafe by the Palms Hotel but back off of the beach towards the road is good for breakfast. Alfreds breakfast sandwich called "the negril" is awesome.
Last trip (June) I must say that Alfreds got most of our beach business in the way of food, I would definitely agree with everyone about the fish and chips there, it's very good. Also we enjoy having a few meals a Sun Beach.
Dinners for us on the beach are usually Momma Flo's / Sun Beach / and Alfreds.
If you venture up to the cliffs please give De Bar a try for dinner and Sips and Bites a try for breakfast,lunch or dinner.
