I have been to many ramen places around the GTA, from the known to be subpar (Ajisan) to the higher end (Momofoku) to the miscellaneous (Kinton, Hakata Shoryuken...). None of them have beat the flavour that I experienced the first time I had the black garlic ramen at Touhenboku. There's just something about the ramen broth that gets me every time. I have never left this place feeling unsatisfied or regretful that I chose to eat there.
With that said, I think they really need to work on some of their smaller side order dishes. The ebi mayo I had once was pretty bad and they can do some much better for a price tag of $9 dollars.
