Easily one of my favorite ramens in Tokyo, Ichiran is a chain of restaurants serving ramen in the Tonkotsu (pork bone broth) style. This location is one of their busiest and often has a line extending onto the street, but the wait is worth it. The small dark basement space has two rows of bar style seating, with little dividers – so you can eat alone or with friends. Ordering is an experience in itself; use a ticket vending machine to purchase what you’d like, then fill-in an order sheet specifying the texture of your noodles, the oiliness of your broth and just how spicy you’d like it. Be sure to slurp loudly as you enjoy the rich pork flavors in the style made popular in Kyushu! Open 24 hours.
