So we spent 50 minutes on the AREX to get to Hongdae. At The station (I think Hogndae Universiy station), we spent a good amount of time looking for lockers and waiting for them to become available. But after, we exited the station and had our first taste of Seoul. It definitely seems like Japan, but less cleaner. Mainly there were a lot of restaurants and kids performing in the street. We ended up eating at a KBBQ place where stones are used as the grill.
