Jjukku Jjukku Jjukkumi is a jjukkumi restaurant in the Cheonho-dong jjukkumi alley in Gangdong-gu, Seoul, serving jjukkumi-bokkeum and jjusam. You wrap the spicy seasoned jjukkumi in perilla leaf and ssammu with mayonnaise, then finish with flying fish roe cheese bokkeumbap. There is a wait at meal times and on Sundays, and the shop runs three branches lined up almost side by side in the alley. The portions of jjukkumi and jjusam are small, so they are not enough for a meal.
