Went twice, once for soft opening and once recently. No doubt the signature live up to expectation as the ramen survives in the competitive market of Tokyo and while being recommended in the Michelin Guide (not in the star rank, just gourmet serction). But I can only give 3 star as the customer service and wait line issues is not worth your time and money. This is all due to lack of training of the staff and incompetent management. The ramen hype for Toronto has been lit again and I suspect more Japanese chain would come in the years to come.
