People rave about Golden Turtle, but I'm a Pho Tien Thanh girl after trying both.
The service is great and so friendly, and the pho is perfect.
I usually get #13, rare beef and tendon pho, and Tien Thanh nails it.
They give a generous portion of tendon and beef (much more than I got at Golden Turtle) and they have that broth that makes you want to keep drinking more even though you are, indeed, very full.
I just came back from my third visit in a row and caught celebrity chef Susur Lee and his family dining there. I didn't believe it when I read the reviews and interviews but I've seen him there in person with photo evidence to boot!
If you want cheap, quality pho, with great service in Toronto this is your place!
