The first thing to know about San Omakase is context: an intimate, tightly controlled room in Rio de Janeiro, Brazil, matched with the ambitions of a sushi-focused restaurant. What matters most is fish quality, rice craft and a tightly paced counter experience; a luxury, special-occasion price point makes it a restaurant to choose deliberately, not accidentally. Its one-star standing makes it a serious address: polished enough to plan around, but still best judged by whether the kitchen's point of view matches your tastes.
