Toronto is replete with great food, and superb sushi. Yuzu No Hana most definitely ticks all the boxes for both top quality fish and a far above average variety. The dining room is charming with the traditional Japanese flair you want. The urban space constraints only enhance the coziness, like it is in many Japanese sushi bars. Service, like everyone else has said, is inconsistent depending on where you look. The host is fast and efficient as are the sushi chefs. The servers in my experience were not. The bus boy serving tea had to grab our server twice for us. Better service would have earned them the fifth star in my book.
Now, on to the most important part... Food
The oyster shooter is a must try. The textures and flavors are incredible. You will love Uni and quail eggs after this one.
The omakse sushi, sashimi, or dinner are the way to go. The variety was the perfect mix of expected and exotic.
Perhaps beef tartare isn't in their wheelhouse. While the quality was good, the beef was chopped so fine it was lost in the garnish.
They have an extensive selection of sake and shochu to complement your meal. It's a great chance to experiment with some pairings too!
Definitely on my list in Toronto. A delightfully delicious and satisfying night.
