Usually I don't review chain restaurants on yelp. Frankly, there's no reason to; their strict adherence to their protocols leaves very little room for actually impressing people or doing anything different.
Is this place different? Not in the sense that it does things that are not allowed - a "rogue" subway.
Simply speaking, it's the best quality Subway I've been to; their staff is friendly, their store is clean, and their bread...let me tell about their bread. I'm not sure what they do to their bread, but it's consistently fresher and tastier than any other subway. I can actually get a regular bread (not toasted)
How do I know? Try the one on Bloor & Spadina and then compare the bread. No competition.
