Ryusenso Busan Yeonsan serves Japanese-style ramen in Yeonsan-dong, Busan. The menu includes Ryusenso Asari, made with a clam broth and soy base, shio ramen, and tonkotsu ramen, all served with medium-thick noodles cooked chewy. There are bar seats for solo diners and tables for four, and the menu is written in four languages. Most seating is at the bar, so the space between seats is narrow.
