This is part of a global Japanese chain. They maintain Japanese levels of service, with very attentive waitstaff. As with many ramen joints, the noise level can be high, but that's just because ramen has a way of loosening people up (I'm sure the sake on the side helps a bit in this department).
As for the food, it's legit ramen. The tonkotsu broth is rich and creamy, as it should be. My only complaint is that it was a little too salty for my taste (I got the spicy miso tonkotsu broth). The real treat was the toroniku served on the side: a plate of braised, sliced pork jowl. It was perfectly seasoned and fork tender. I also added a side of the char siu, which was also tasty, but a bit tougher than the toroniku.
If I lived in Toronto, this would definitely be one of my go-to spots for when I need a ramen fix.
