Ichiran Shimbashi is a ramen shop in the Shimbashi area of Tokyo that serves tonkotsu ramen. The rich tonkotsu broth comes with chashu, and you adjust the strength of the secret sauce to your liking and order at a ticket machine at the entrance. Seating is in single-person study-carrel style, so you can pass your requests to staff without face-to-face contact, and food tends to arrive right after you order. At lunch or on Fridays, waits can run from 20 minutes to about an hour.
