1-1-10 Kabukicho, Shinjuku Golden-gai 2F, Shinjuku-ku, Tokyo, Japan
Ten-seat 24-hour ramen shack on the 2nd floor of a Golden Gai shanty, famous for sugoi niboshi ramen — a pungent broth boiled 12 hours from 20-plus types of dried fish — that helped kick off Japan's niboshi-ramen boom.
Haven't been here myself — came recommended from someone I trust.
