The popular ramen shop is located next to Shinjuku Gyoen Park, a short distance from the station. It mainly attracts tourists, but there are also some Japanese customers. The shop is not very large and has limited seating, and it has received Michelin recommendations, so there might be a wait.

They offer three main flavors, all of which can be ordered in larger sizes for an extra charge. However, it's confusing that the salt flavor was sold out while the option for an increased portion of the salt flavor was available—perhaps they want to boost the average spending per customer? As for the taste, everything is quite good, the broth isn't overly salty, and the chashu is tender. If there's not much of a wait, I'd definitely consider going back.
