Toronto has quite a lot of ramen options and this place is one of the best ones.
We ordered two dishes: The Tonkostu black is really good but a bit salty. The spicy tan tan apparently is only offered in limited qualities per day, but we managed to order it and it was really good. I actually liked it more than the Tonkotsu black so I would highly recommend trying it. Overall the broth and noodles are very delicious so I think any dish you order would be good.
This place is pretty busy, we went around 6pm on a workday and it was already full. We only waited about 10 mins for a seat though.
