I've been to the downtown location and it was stupendous! The new Yonge and Finch location was a godsend for the uptowners.
I tried the spicy ramen, it was the perfect amount of heat for me, I'd compare it to medium-hot level of chicken wings level of heat. The broth is worthy of emptying your bowl and the noodles had that nice tender resistance while chewing. I would put the noodles in the same league as Kinton or Kyouka as I had ramen from there within the last few weeks to compare.
Small seating area, service was pretty good, not as good as the downtown location I thought, but still tentative and kind.
