Big Sushi is my favourite "everyday" sushi spot in Toronto.
Fresh ingredients. Good portions. Solid presentation. Definitely well priced. It's like they took a page out of Goldilocks and the Three Bears.
Sushi Island on College has better veggie/vegan options, there are definitely higher-priced joints around town that offer better presentation and ambiance as well. But, on a random run-of-the-mill weekday, Big Sushi's holds it down. Do it!
