Even though i have been recently informed that i, along with almost every other white person, pronounces pho incorrectly... i still LOVE it, and pho seems like a pretty laid back kind of food... so i don't think it minds much.
Pho Asia 21 isn't my favorite pho place... but it's close to work, and is damn cheap. which is excellent for those days when money is tight. I've never been a big fan of the beef that comes with most pho. I always find it rather tough, and lacking in flavor. So it's nice that pho asia 21 offers a pho with just the rice noodles and beef broth.
The servers are friendly enough.. and the food comes out fast and hot.
If you are in the king and dufferin area and want a little Vietnamese i would recommend checking this place out.
