Komoro Soba is a soba shop on the Yaesu side of Tokyo Station that serves soba and rice bowl sets. You can order kakiage soba with a tendon set, or soba paired with a katsudon bowl. Buy a meal ticket from the vending machine at the entrance using cash or a transit IC card, then sit at the standing area or the chair counter inside. Around 8 a.m., the line stretches outside the entrance.
