All this talk about "best pho in Toronto" is surely an exaggeration. It's not my favorite, but I accept that there are subtle differences in every kitchen. Rua Vang is not bad, you can't go wrong with pho. The non-pho dishes leave a little to be desired, so don't get your hopes up if you're planning to skip the soup.
One extra star for them is for the patio, in the summer it's the perfect spot to relax and cool off (get a milkshake to double down on the experience).
And if you're ever back in the area for a second round, try Pho Tien Thanh instead, a block south. I say they're better, but of course opinions are divided.
