Rishiri Ramen serves spicy ramen with green peppers in a back alley of Kabukicho. Its main dishes are the spicy soy sauce-based Orochon Ramen and the miso-based Miso Chon, with spice levels from 1/4 to 9. The shop takes cash only and is open from late night until the next morning. The interior is hot and humid because it is not well ventilated.
