Koshun Apgujeong is an izakaya near Apgujeong Station that serves Japanese food and drinks. The menu includes aged sashimi, Hanwoo tenderloin gyukatsu, and abalone offal pasta, along with sake and highballs. Reservations are available through CatchTable, and the open kitchen lets diners watch the chef cook. The omakase course consists only of chicken dishes, which feels heavy to finish and small in portion.
