Kokura is a Japanese ramen shop near Waterloo Station in London that serves tonkotsu ramen, chicken karaage, and gyudon. Its signature tonkotsu ramen comes with pork bone broth, chashu, and a seasoned egg, and customers order at the counter and pick up their food when a buzzer goes off. The ramen arrives shortly after ordering, and the seasoned egg is soft-boiled. The broth and gyudon are on the salty side, and the portions of ramen and rice bowls are small.
