I almost refuse to believe that I haven't written a review for Rua Vang yet. I eat here at least a couple times a month. Not because it's the Best Pho Ever of All Time. But because it's yummy, it's near home, and it's across the street from yoga.
Not having been to Vietnam, I can't properly comment on authenticity but I can comment on yumminess and the pho here is yummy. I always get exactly the same thing (rare beef pho) - if I have a hankering for anything else it doesn't even occur to me to come here. Flavourful broth, thin slices of pink beef that cook as they float, and a smattering of sprouts and basil? Heaven.
This is the only pho place I've tried that has a patio (and on a side street, no less!), which earns extra points (and I submit that there is nothing weird about craving a steaming hot bowl of pho when it's 32 degrees outside).
