If you’ve never tried a kaiten-sushi (conveyor-belt sushi restaurant), don’t miss this place – most dishes are a mere ¥146. Not the best sushi in the world, but it’s cheap, reliable and fun. It’s also easy to eat here: you just grab what you want off the conveyor belt. If you don't see what you want, there’s also an English menu to order from.
Musashi is just outside the entrance to the Sanjō covered arcade; look for the miniature sushi conveyor belt in the window.
