Santouka is my favorite ramen place of all ramen places I've been to in Toronto. Sure I could fly to NYC or other places in the world, but what they offer is the most consistent and tasty ramen in the style that I expect.
What I like eating here is the Tokusen toroniku. The toppings: pork jowl, bamboo shoots, seaweed, scallions are served separately so that you can adjust to your liking. The ramen is chewy and substantial, and the broth is wonderfully creamy and tasty. The pork jowl is tender and fantastically seasoned.
In addition, when you're really hunger, the ikura gohan is a tasty side of salmon roe, shredded egg and seawead on bowl of rice.
I am not big on lining up for food, so when the line is 5-15 minutes it is worth it. I would not lineup an hour for something simple like ramen.
