Take the subway to Incheon University and walk a short distance after leaving the station. The campus is not big, but the layout is reasonable, the scenery is great, and near the sea, there are birds like pigeons and seagulls. You can also encounter pictures of your son traveling with you. They are very lovely. You can eat in Incheon University canteen when you get to the meal point. The price is cheap and there are many kinds. The taste is very good. Besides the subway money, there is no extra cost. It's worth going.
