Set in Rio de Janeiro, Brazil, Ryu Restaurante - Barra da Tijuca reads as a Korean restaurant rather than a generic listing. The draw is Korean flavor, rhythm and shared-table energy; at a comparatively accessible price point, it should be judged as a smart choice when you want something considered without turning the night into a major splurge. It is most compelling for diners seeking flavor, texture and a point of view rooted in cuisine rather than decor alone, especially if the night calls for something more considered than a safe default.
