I spend a lot of time in Toronto for business and have to watch my intake of crap food as being on the road and living in hotel rooms it is very easy to make bad choices. So I tend to go for sushi as much as possible and having tried a bunch of places in downtown /Yonge St area of Toronto none can come close to Kokyo. The Sashimi is is ridiculously good, always tasting fresh and giving you good choices including fish you won't find and the regular sushi joints in town.
The rolls are sensational the miso soup is perfect.
I have eaten sushi in New York, San Francisco and LA and I have to say no place has come close to the quality I have enjoyed here.
The best ... period.
P.S REALLY friendly staff too!
