Oshien sits across from Munjeong Middle School and next to Taieo Gongwon in Munjeong-dong, Seoul, and serves jjajangmyeon, jjamppong, and tangsuyuk. Its honghap jjamppong is known for a thick broth, and its junghwa bibimbap is the only version of that dish in the neighborhood. Food is cooked in the store rather than delivered, so orders come out without a long wait, and on Wednesdays a day-specific menu brings together kkanjo saeu, bokkeum bap, jjajangmyeon, and jjamppong broth. The dining room holds about ten tables, so it does not suit those who care about restaurant atmosphere.
