Katsumansion 10 is a restaurant in Haeundae, Busan, across from BEXCO, serving Japanese-style tonkatsu and Sapporo ramen. It offers anshim katsu, rosu katsu, and modum katsu, plus curry udon, and tonkatsu orders come with rice, side dishes, and soup. On weekend lunchtimes, even with a third-place wait, ordering first at the kiosk and writing down your number made the line move quickly. All tables are bar-style, so the interior is small.
