Jjubul & Jjubul is a restaurant in the basement of COEX Mall in Samseong-dong, Seoul, serving jjukkumi bokkeum and other Korean dishes. The jjukkumi bulgogi set comes with chadol doenjang jjigae, and the gopchang jjubul set comes with gopchang jeongol and tteokgalbi. At lunchtime the restaurant is crowded with customers, and the jjukkumi has a moderate spice level that is not overpowering. The dining room is busy, so eating quietly is difficult.
