Beautiful area filled with cafes and small shops, very walkable. You can see some people wearing traditional Korean clothing walking around, as you can rent them here.
Myeongdong is the most crowded shopping street in Seoul. It has many branded clothing shop and street eatery, but the experience could be unpleasant due to the crowd.
An factory themed restaurant serving pan of cheese. It's pretty nice actually, and the environment is dimly lit. The cheese pan might seems small, but it is more than enough for 2 persons.
