One of the best pho restaurants in Toronto. Cheap, fast, tasty. Well worth it, and conveniently located on College so you can just take a streetcar across.
The service is not amazing (hello? It's under $10), but the food is good and that's all I care about.
Update: I downgraded it to 4 stars because I recently visited and they were stingy on the beef, it was overcooked and while the shakes were delicious and the broth was still flavourful, I found a better place:
Tien Thanh @ 57 Ossington
The beef is out of this world, and the broth is so flavourful it makes me cry tears of pho.
