as it turns out Sonoya is essentially Kenzo ramen so food quality I would say is just the same. I have not been to Kenzo in a while, but to me this was the best ramen in Toronto before all the other ramen shops in downtown started sprouting all over the place.They didn't even have Tonkotsu ramen in the menu at that time. When they finally did, I was less than impressed.
For this trip, I got my go-to Kenzo order which is the Sapporo ramen and to be honest it was great to not order the Hakata tonkotsu style ramen for the first time in years, which is the only thing I order in any ramen place. the Sapporo ramen reminded me why I loved Kenzo in the first place. Loads of ingredients, and I love the smokey charred flavor they get into the bowl. Good broth, nice bite to the noodles. The bowl was huge. I don't recall it being so huge but I think I was more full here than at an AYCE.
Big bonus is there are a lot of food options around the area and in First Markham place, so getting good seats was not an issue. Downside is this area is such a pain to get parking at.
