I have been a fan of Santouka since I first tried it in the Misuwa food court in NJ so I was happy that they have finally decided to come to Toronto. I have tried all the other ramen places in Toronto and I have to say that Santouka is the best among the wide selection of Japanese ramen houses in Toronto, but its no Ippudo. Let me first clarify that my ramen of choice has always been the miso infused variety and NYC Ippudo's Akamaru Modern ranks among the best I have tried but Santouka comes close but not that close.
My only gripe with this place is the long wait. Given the popularity of ramen in Toronto and the number of patrons that are so willing to line up for some ramen everyday they should expand or open another location so that everyone enjoy some great Hokkaido ramen without having to wait in the bitter cold!
