Hakata Bunkō Yeouido is a Japanese ramen restaurant in Yeouido that serves tonkotsu ramen and mazesoba. The ramen comes with thin noodles in a rich, savory broth, while the mazesoba is served without broth, using thick noodles and a spicy seasoning. The shop has only counter seating, so a line forms at lunch, though the tables turn over quickly. The pork aroma and heavy flavor typical of tonkotsu are divisive.
