The menus clearly state that halal food is served.. Halal Japanese Curry Rice available here.
The curry sauce they use is delicious, and the idea of being able to completely customise your own curry is neat. Everything is cooked to perfection and relatively cheap- but be careful, the add-ons can bump the price up quickly because there are so many great choices to add on! English, Portuguese, Spanish, Korean and various other languages available on the menu makes ordering for tourists and absolute breeze!
