On the Saturday night we were there, we went to the Dongdaemon market, which is the biggest market in Seoul. We had some great food there (pictures tomorrow). What you see here is the Migliore shopping center, which basically acts as an indoor market. Inside are 8-9 floors of sellers selling mostly copied clothing, bags, etc. This particular shopping center (there were many in the area) is always mentioned in Japanese magazines that talk about shopping in Seoul.
