Hakka Sushi is a sushi-focused restaurant in São Paulo, Brazil, and the useful context is what kind of evening it seems built to deliver. The draw is fish quality, rice craft and a tightly paced counter experience; at a polished mid-to-high price point, it should be judged as a polished dinner worth planning ahead for. It is most compelling for diners seeking precision, pacing and quiet focus, especially if the night calls for something more considered than a safe default.
