Simyadangsikdang Gieok is an izakaya in Haebangchon, Seoul, serving aged sashimi and mackerel bo sushi. The sashimi features thick cuts of seasonal fish such as yellowtail, tuna, and herring, and the mackerel bo sushi requires a reservation in advance. Reservations through CatchTable or Tableling can seat guests in the basement room, and the drink list includes sake, wine, and highballs. The space is small, so the area between tables is somewhat noisy.
