Locals are thrilled: finally, a date-night restaurant in Puerto Iguazú. Although the high-ceilinged split-level cabin seats too many to be truly intimate, the owners make up for it with well-spaced tables, discreet service, and low lighting. Softly gleaming timber from different local trees lines the walls, roof, and floor. Local river fish like surubí and dorado are the specialty: have them pan-fried, or, more unusually, as pasta fillings. Forget being romantic at dessert time: the chef's signature dessert, caayucayari, with almonds and yerba mate, is definitely worth keeping to yourself. Reservations are essential on weekends.
