I like this location much better than the one downtown. I typically go during busy hours, but even then - surprisingly there isn't much of a wait! If you haven't been to these types of Japanese restaurants, be warned. It gets VERY loud as the workers are constantly shouting (in Japanese) goodbye/thank you etc. It can be overwhelming at times if you're trying to have a proper conversation, but normally it's amusing.
The food is delicious, but it can get pricey especially if you plan on ordering a lot. A must on the menu are the stuffed oysters!! I forget the actual name... But THEY ARE INCREDIBLE. I dream about these. I don't typically like oysters, but I could eat 4 of those things myself. It used to be known as Guu (I don't know why they changed it?!) but it's a cool spot to grab good food and some drinks with friends. Definitely a go-to spot for me in North York.
