Sushi Tsubasa is a sushi omakase restaurant on the first floor of a villa on a back street just off Sinsa Garosu-gil in Seoul. The shari has a strong vinegar and salt profile that pairs with neta such as herring, mackerel, doha shrimp, and uni, and the restaurant also serves dishes beyond sushi. The lunch omakase moves through sushi and a series of dishes, with enough volume to leave you full after the meal. Because the shari's vinegar and salt are strong, it tastes sour and distinctive.
