Jaja-men (じゃじゃめん; noodle with miso and minced meat) joints are all over town, but this hole-in-the wall is still the leader. Ordering is a breeze: just ask for shō (small), chū (medium) or dai (large). When you're finished, crack a raw egg (¥50) into the bowl and the staff will add hot soup and more of that amazing miso paste.
It's down a side street opposite Sakurayama-jinja; you'll know you've found it when you find the queue.
