Tsukemen ramen serves noodles in one bowl and the broth in a different bowl. Thick noodles are dipped into the tonkotsu (pork) and smoky fish broth. If the soup is too rich, add a splash of vinegar to brighten it up. Powdered smoked fish flakes can also be added to the bowl to make it richer. Rokurinsha is one shop that excels at tsukemen at Tokyo Ramen Street, in the basement of Tokyo Station’s Ichibangai shopping arcade which is centrally located. The shop is open for breakfast, a rarity. While you are here, be sure to check out the shop across the aisle, Shokoku Gotochi Plaza, as it has a wide variety of regional Kit Kats.
