I was in Japan a few months ago, and this place holds true to making authentic Japanese ramen.
I love the decor. Very modern, and very hip. Wicked vibe. The seating is small, but the staff do a great job with using the space they have. They'll take your number down, and call you when you're up next. Kensington's not a shabby place to wander and kill some time.
I've been here twice. Their gyoza's were delicious. They even have takoyaki! Their ramen noodles were cooked to the right amount. I hate it when noodles are under-/over-boiled. The ramen broth is not overly salty like many places. Great service.
If you love unagi, go here. They serve an Unagi Don Bowl, which gives you more than your craving of unagi.
Highly recommended.
