I was thinking to walk all the way to the N Seoul Tower yesterday but i think it was a good choice to go by cable car and came down walking as the view was really nice from a spot on the way down. After going to Namsan park we just walk all the way to Namdaemun market. I was expecting to see part of the gate but it was all covered because of the construction. After that Itaewon and Hongdae both are really nice at night especially hongdae.
