I am a chicken Ramen lover and this is hands down my favourite place for Ramen in Toronto. Every time I crave ramen it's Touhenboku's that I want. My go-to is: Thick noodles, Sea salt, chicken broth/ meat, and Spicy red. The service is friendly; the flavour is simple, and I almost want to say delicate, compared to other ramen I have tried around Toronto. As a regular customer, I truly appreciate the consistent flavours I get every time. Although they have a fairly small menu it's great to see a vegetarian ramen option available as well.
The only downsides I've ever experienced are having to wait in line during busy hours, once or twice, at the Queen location (Nothing new for good food!). Also, the spicy option is not spicy at all in my opinion. If that's a big deal for you then this ramen might not be to your liking.
My only suggestions: bring your ENTIRE appetite and try the "Yakitori Don" too if you can!
