This restaurant opened in 2016 with a concern for those who have dietary restrictions, but still want to enjoy delicious ramen. It is still rather rare to be able to enjoy Halal or vegan ramen in Japan.
Their ramen is made with sea bream, wagyu, and fresh vegetables. Everything they serve is Halal!
They also have vegan ramen for those who do not consume any animal products.
