Hopfen is an old ramen shop next to Meiji Jingu Stadium in Sendagaya, Shibuya, Tokyo. It is open 24 hours and serves oily shoyu-based ramen and moyashi ramen. You pay first at a ticket machine in front of the shop, then staff show you to a seat; the first floor is standing-only and the second floor has seats. The broth is strongly aromatic and a little heavy, so opinions are split.
