Sato is a small, stylish izakaya tucked beside Ryogoku Station, run with a fisherman's-market sensibility that has built a loyal local following since opening in 2012. The narrow interior centers on a counter where the chef preps sashimi and grills to order, giving the room an intimate, workshop-like feel suited to quiet dinners with friends. The kitchen builds its menu around whatever fish is freshest that day, plating it as sashimi, simmered dishes, tempura and hand-formed nigiri, paired with a rotating selection of Japanese sake and shochu. Reservations are strongly advised, as the handful of seats fill quickly with regulars.
