Markets are not the same hour
Namdaemun runs early; Gwangjang runs afternoon into evening. Tongin’s coin lunch works inside that market, around noon. Mangwon is the west meal: one noodle, fry or jokbal stall, then back to Hongdae — not Gwangjang as well. Seongsu is not a restaurant list; one drink in the warehouse lane, then Seoul Forest. Euljiro nogari is the other centre-axis meal — this or Gwangjang.
