Sinseolgung is a traditional Japanese restaurant in a building next to Seoul Oncheon near Hagye Station in Nowon-gu, Seoul. It serves thick, large-cut sashimi and the Sinseolgung set course, with hoe that is chewy rather than tough. The dining room is large and there are several rooms for groups, and the Seoul Oncheon parking lot is available. There is a break time, so you need to call before visiting.
