Isorabo is a ramen shop in Yakuin, Fukuoka that builds its broth from sea bream and seafood. Ordering the sea bream shio ramen and shoyu ramen as a set brings rice as well, and the remaining broth can be poured over it to eat like ochazuke. Orders are placed at a vending machine, and the shop opens early in the morning for an early meal. If you are sensitive to fish aroma, the scent of the ramen and the ochazuke can be overwhelming.
