Aoriui Haengbang Bulmyeong Yeouido is a Japanese ramen shop in Yeouido that serves tonkotsu ramen. The tonkotsu ramen has a rich, savory broth with deep umami, and the noodles are chewy. The shop stays quiet on weekend lunches and dinners, and it has seats that suit eating alone. The base flavor is slightly spicy, so those who cannot eat spicy food should take note.
