I am not a sushi expert so I can't comment whether this is the "best" sushi in Toronto (which must be quite an honour), but I can say that this little restaurant tucked almost across the street from a Park n Fly, is a welcome port in any storm, especially when coming off a long flight and landing at the labrynth they call Pearson.
I had a choice of two sushi places that night - this little place or a box-store sushi place close by.
Glad I chose Sushi-Ya. Intimate, warm, friendly, and good sushi. I only did take out, but even that was a pleasant waiting experience as I enjoyed a lime flavoured glass of water and a delicious sample of spicy noodle soup.
