There are several inexpensive comedores in the area that serve typical local food, but if you'd prefer a sit-down dining experience, there are also a few restaurants.
Ellen's Place - located inside of Pirate's Den, which is about a 5 min walk from the hostel (turning right on the main road, following the curve, and on the other side of the street, just before the paved turn off to the beach). Vietnamese food, closed Sundays. They have a lovely spacious seating area with an oceanview.
