This is one of those places that you would think is open 24/7. It's not. For that, you need to go to the train pho place on Spadina.
I usually get the vermicelli bun ($7.25) with the grilled pork, chicken, beef, whatever I'm feeling that day. Sometimes get the Pho w/ rare beef which is decent. Spring roll is nice, although I'm not sure what's in it. The resto itself is probably a bit below average in terms of cleanliness. I worry how often the seats are cleaned (if at all). So don't linger too long, which I think is what they're aiming for anyways.
It's consistent, it's fast, it's average priced. It's where you go when you want to get something quick but not a food court, something that's actually cooked for you.
