I know of only 2 Japanese ramen places in the GTA. Kenzo and Ajisen. I'd say Kenzo is definitely much better than Ajisen. It's not the best but it's not bad. I had a craving for tonkostu Ramen and this place made my day. I've had tonkotsu Ramen in Japan which was really awesome and obviously this aint as good. But after eating it you don't crave for it as much anymore.
I only order 3 types: tonkotsu, satporo and the king. All of them very satisfying in their own unique way.
if anyone knows of another ramen place I'd love to try it.
