Shin-chan Ramen
A popular "chan-kei" ramen shop on the 1st floor of Ciel Shinjuku, 3 minutes from Shinjuku Station south exit. Soy-sauce broth filled to the brim, chewy flat noodles and a generous pile of chashu define the bowl; regulars customise with back fat and a raw egg.
Reviews praise the brimming broth, generous chashu and the raw-egg pairing. Many note it is clean and easy to visit solo.
