Cha R Yongsan is in the basement of the Amorepacific building near Sinyongsan Station, serving American-style Chinese food. The menu includes yuringi, Shanghai seafood jjamppong, and seafood chow mein. Curtains divide the seating, which makes it suitable for using a separate space for group gatherings, and outside tables are also set up. The sweetness is strong across the whole menu.
