There are quite many entrances and you can enter the mall from anywhere you want. The containers are really special and you can see people taking photos in front of those blue containers. You can find stalls where clothes and shoes are sold at an affordable price and the options are also much more than you expect. It is because the space is really big and it is not as crowded as Myeongdong or Hongdae streets. Especially during weekdays, there are not many people at Common Ground and you can move anywhere you want really fast.
Also, if you go to the second or third floor of the containers, you can find some restaurants and rooftop cafes there. I had never tried those cafes before but I think they worth a try since I always got recommendations from my Konkuk friends.
