Rushing is a Chinese restaurant on the B1 floor of Seoul Square, connected to Seoul Station Exit 9 by an underground passage. It serves tangsuyuk, jjamppong, and course meals, including thick-cut pork tangsuyuk and beef jjamppong with chuck flap, and single dishes can also be ordered. The restaurant has many private rooms, so groups can dine in a separate room when booking, and bringing your own wine comes with free wine glasses. Portion sizes are on the small side.
