Ramen Tatsunoya Shinjuku Otakibashidori is a ramen shop in Shinjuku Otakibashidori that serves tonkotsu ramen and pork horumon tsukemen. The horumon tsukemen is eaten by dipping noodles into a thick, oily broth, and the remaining broth can be used to make porridge on request. Customers order at a kiosk before entering, hand over a ticket, and wait, and the food arrives as soon as they sit down. The tonkotsu ramen feels greasy, and some of it is left uneaten.
