I used to be a Big Sushi zealot, but after hosting an epic sushi night while watching Jiro Dreams of Sushi, I have converted to the calling of Sushi on Bloor. It's cheap, they're fast, the quality of fish is on par if not a a smidgen better than Big Sushi aaaannnd they're about a block closer to me. So win, win, win and win.
Bear in mind I've only done takeout so I have little to no experience with the dining room itself. Although the couple times I've been in there to grab my food, it's been super packed with a cluster of people jamming the door. In fact it feels like you're in a crowded little dim sum place on an early Sunday morning with the sea of voices and clinking of tea cups and plates. Not the greatest, but not necessarily unpleasant if you're used to how we asians do.
I recommend. Don't let the tacky sign dissuade you.
