We were looking for a nice steak meal in Arenal and our resort recommended Benedictus. Being that it was low season, we were the only couple in the restaurant after the other couple inside finished paying their bill upon our entry. Our server, Oscar, was very friendly and provided great service. The menu offered good variety. We ordered the shrimp and tenderloin as well as the fish with avocado sauce. The avocado sauce was quite interesting, yet good, and we thought the shrimp were some of the best we had ever had. We spoke with the owner of the restaurant while waiting for our return taxi, who was very friendly and offered us a digestif on the house! He has many plans for expanding the restaurant to increase their ability to provide their own ingredients, pretty much all ingredients save for fish, as this is impossible due to their location atop a high hill. I believe that the views would have been spectacular at sunset, and Oscar told us that he often sees monkeys and toucans right outside of the restaurant balcony.
Bottom line: Recommended. This was a very unique atmosphere and an impressive meal for such a small laid-back town in CR.
