I frequent Mekong River at least once a month and they are generous with their meat portion for the Pho (I typically get the house special, or the rare beef and tripe). You can't order a small pho for take out, only medium and large.
Their fried spring rolls are very good also. Not as great as the golden turtle (on Ossington), but really good for Etobicoke!
The Vietnamese cold coffee is really good also.
The only thing I would give a lower rating would be their milkshakes. I've had the mango a few times and it's not bad... but not as good as your better Pho joints.
