Sushi Rikai is a Japanese restaurant in Sinsa-dong, inside Garosu-gil, serving a dinner omakase. The omakase includes sushi such as unagi, otoro, uni and toro, along with kaiseki-style tsukami. The course menu changes entirely each month, and dinner runs as a 1-hour-30-minute course. Even at the counter, the portions are enough to leave you full through the final dish.
