Akai is miles ahead of anything else in the Annex. It's a little out of the way on the corner of Harbord and Major, and completely worth the 5 minute walk.
The Annex has no dearth of second-rate sushi restaurants -- the best of them boasting shoddy service and run-of-the-mill fare. It's really nice to have an option like this in contrast to the rest.
The perfect seared sashimi, quaint and traditional decor, mom and pop ownership, and friendly and present service will quickly shatter your new-gen/sushi-on-bloor paradigm.
