Located where Hanoi was, this newly opened Phở House is the real-deal. Perfect Phở and they even had traditional drip-coffee with condensed milk that you can pour over ice.
What I really appreciated most about Phở Vietnam is that they did not also offer 'Thai', 'Chinese' or (heaven forbid) 'Italian'. It is what it is... and after my first trip, I say it's damn good at that.
