Located across from BanReservas on the main road, this is an excellent seafood option, notably for its paella (the owner is Spanish), which could hold its own against any in the mother country. If you beg, they'll even serve it for one person (solo travelers, rejoice).
Locals give the pizza (RD$300 to RD$640) high marks, too, and the coconut flan is a nice way to end a meal.
