We never expect that katsu would go with well with ramen, but it was!! Also, their house curry is very tasty, so my kid had two bowls of this. For "Fantastic 4", its name explains! Must try!!

I don’t normally order katsu, but the cheese katsu here was so deliciously light and crispy! Our 11 month old son ate two pieces of california roll too. Can’t wait to take my parents here!
