Lotte World Mall is one of the latest shopping malls in Korea opened in October 2014. In the Lotte World Mall, you can find a cinema, ticket counter on 5th floor, cinemas on 7th to 12th floor. A lot of English movies (with Korean subtitles), I think nearly 20 screening rooms, tickets around 10k per person, a deal for food: 2 drinks + popcorn 8500 Won.
