Over the last few years, izakayas have really become a hot trend of Toronto. Many places are just trying to cash in on the bandwagon, serving mediocre food for a tapas bar price, but Shinobu is definitely the exception. There is a reason why it is rated so highly on yelp.
The restaurant has the perfect balance of quality, taste and price. The sashimi is incredibly fresh, the appetizers clearly have a lot of care put into them, and all for less than what higher end restaurants will charge.
Definitely try the shimesaba (flame torched mackerel), chicken karaage (tempura fried chicken), and volcano rainbow roll (drizzled lightly with a honey sauce, then torched for caramelization). If you're feeling like a treat, order the supreme nigiri or sashimi and see what actually fresh fish tastes like.
Do not go to shinobu if you aren't an adventurous eater and don't like fish.
