This place has good cuts of fish that are sizable and fresh. That's my main criteria for any sushi place. The nigiri was quite good, and more filling than it initially looked. I had the Edo combo, which was satisfying. My only criticism was that the nigiri and roll combo included a sushi roll of avocado -- no other ingredients -- which I found kind of pointless.
If you are looking for a wide variety of sushi preparations, this isn't your place. You are mainly limited to nigiri and a dizzying list of rolls. No chirashi or much in the way of sashimi at all. Omakase didn't seem to be a menu option either, but to be fair, i didn't ask. There are some other options, like a "sushi pizza," which had cuts of tuna on a fried rice "pizza". The rice was a little on greasy side, even accounting for it being fried.
If you are jonesing for sushi in Old Montreal and you appreciate a fresh, fair cuts of fish, Tokyo Sushi Bar will scratch your itch.
