While I can't consider myself a pho connoisseur, I have been to Golden Turtle several times with friends and have never been disappointed.
The staff are friendly, service is quick and prices are very hard to beat, especially considering its famous reputation. My order has rarely deviated from the Beef Pho and I have yet to be disappointed - rich soup broth is met with ginger, herbs and delicious beef. With the added chili and hoisin sauce it's hardly low-sodium, but thankfully water refills come regularly.
Definitely worth the visit if you're looking for some great Vietnamese or you find yourself on the west end of Toronto!
