Giljo is a drinking establishment in Seoul serving grilled skewers, grilled pollock roe, and grilled mackerel. It has a separate menu for solo diners, and groups can visit, but parties of more than four may have difficulty sitting together. On dates ending in 5, 7, 9, or 2, skewers are offered as a buy-one-get-one promotion, except on Fridays, Saturdays, and Sundays. Dishes take a long time to arrive.
