AquaFoz

Near the Parque das Aves is a recently opened aquarium, AquaFoz (aquafoz.com.br; adult/child R$150/60), which offers beautiful glimpses of what's happening underwater in the Río Uruguay and Río Paraná and, of course, the oceans these great rivers empty into. It's a great place to see the fish that you'll likely find on menus, too, like surubí (a behemoth catfish).
