24-hour ramen restaurant in Busan: Ryusenso Basic & Kara
Ryusenso is a 24-hour tonkotsu ramen restaurant near Jeonpo Station in Busanjin, Busan. I tried the Basic Ryusenso and level-1 Ryusenso Kara for rich pork-bone broth and a spicy variation. Verdict: a handy solo-dining ramen stop for late-night cravings.
