I'm a sushi junkie and generally I'm disappointed by Toronto sushi. And when I say sushi I'm really talking about high quality raw fish and rice - I can't comment on tempura or the other things.
I love Shogun. The sushi here is fresh and delicious, and it is offered in traditional and creative options. And more than that, it is very reasonably priced and served by attentive and smart servers (they remember you and your preferences).
The decor is dated and has signed pictures from celebs from years ago. This doesn't bother me, but if you need slick, modern interiors, then this is not for you.
I go far out of my way to eat at Shogun, and enjoy that dinner time is generally pretty quiet and I never wait for a table.
