Ramen Keisuke Tonkotsu King is a tonkotsu ramen shop in the Orchid Hotel in Tanjong Pagar. It serves basic tonkotsu and Black Premium ramen, and orders are placed by ticking broth richness, oil amount, and noodle texture on a paper form. The space resembles a small traditional ramen shop, and boiled eggs and bean sprouts are free to eat without limit. The shop is small and the wait line is often long, so customers have to wait for ramen.
