One meal
Euljiro is the centre-axis night. It is not a second Dongdaemun, and it is not Hongdae. Walk one stretch of Seun Sangga, come down, sit for nogari, one room, then leave along Cheonggyecheon. Gwangjang is a different meal — do not stack them. After you eat, do not open Hongdae, Itaewon, or the Dongdaemun wholesale floors as another night. In rain, stay under the Seun deck. Save the stream bed until the rain stops. There are many rooms. Sit the first one that will have you, then stop. Do not compare the whole alley and then go to Gwangjang. That turns one centre night into two meals. The stream bed is the way out, not an invitation to Dongdaemun. Once you are on this side of Cheonggyecheon, go back to the hotel.
