Unseo Station is a railway station on AREX. Unseo-dong is the site of Airport Town Square (공항신도시), a relatively new town with hotels and other facilities for those going to or coming from Incheon International Airport. It takes 47 minutes to get to Seoul Station from Unseo Station. There is a large forecourt outside the station with seats and bicycle racks and there are usually taxis there. You need only to walk one block from the station to find the restaurants, and if you look left Lotte Mart (supermarket) is not hard to miss. Lotte Mart has a food court on the 2nd floor if you need a quick meal. When coming back to Unseo from Seoul, make sure you get the train that goes all the way to the airport, as the other one terminates one stop earlier in Geomam.
