Hiro is in my top 3 list for Toronto sushi restaurants! The chef's choice platter is the way to go or the Omikase style if money is no object.
I go to Hiro more often than the other high end sushi restaurants because the $/value you get for such authentic and high quality Japanese style sushi is unmatched.
The ambiance and feel of the place is also very authentic, just like in Tokyo.
