Kikanbo in Kanda, Tokyo, is a miso ramen shop where you choose between spicy heat and the numbing tingle of sansho pepper. The special ramen comes with thick chashu and bean sprouts, served with thick noodles and a rich broth. Buy a meal ticket from the vending machine next to the shop first, hand the ticket to the staff, and you are guided to a seat at the counter. The waiting line runs from 40 minutes to over an hour, so you need room in your schedule.
