Differences and Characteristics from the Actual Store

• Soup : The restaurant’s soup is characterized by a rich and complex flavor achieved by simmering pork bones, chicken carcasses, and seafood for many hours. While the instant version reproduces this flavor, the aroma and depth of the freshly made soup at the restaurant are exceptional.
• Noodles : The custom-made thick noodles from Asakusa Kaikarou, served at the store, are attractive for their strong chewiness and rich wheat flavor. The instant noodles are made to approximate the texture of the store’s noodles, but the elasticity and smoothness of fresh noodles can only be experienced at the actual restaurant.
• Toppings : The chashu, menma, and flavored eggs at the actual store are each made with the dedication of a specialty shop. In particular, the tender buta hogushi (shredded pork) is a topping unique to Rokurinsha.

• Morning Tsukemen is a Good Option : The shop is open from 7:30 AM and offers a lighter “Morning Tsukemen” that is different from the regular menu. Aiming for the morning hours when the line is relatively short is one strategy.
• Don’t Buy Your Ticket First : The rule is to line up and purchase your meal ticket only after being guided by the staff.
