This place was a secret gem on the coast and well worth the trip off the highway to get to it. Guards will let you through the gate if you tell them you are there to eat (it seems to be an apartment/condo complex.) . The food was outstanding, and the mojito was the best I ever had in my life. Perfection, really, from a very small place. (photo is of the beach below the resort.)
You can walk up to the restaurant by the pool from the beach. Nobody seems to complain if you swim there too, especially during the week when the place is deserted. There is a small playground on site too. Reasonable prices and tasty. Try the Corvina sandwich and fruit juices.
