The seafood here is perhaps the best in town, which is obvious from steady stream of locals. Try the charcoal-grilled whole fish, large prawns, crab, and squid—all fresh and accompanied by a delicious chili sauce. The decor is nothing special—of the metal-table-and-plastic-chair variety—but there's some outside seating under the trees. The restaurant next door, owned by the same people, has an air-conditioned dining area if you really can't take the heat.
