I've seen some reviews here accusing pho hung of not being authentic, which is totally bogus. The food here is delicious, affordable and completely authentic. In the 50 or so times I've been here I have never left hungry or unhappy.
A couple notes, take out is super quick, but always smaller portions than eat in. This is the original location, where the founders son still works, the location in china town is the second location. And finally, it's pronounced FA, not FO, try ordering it correctly and you'll be surprised how friendly the staff can be.
Try #22! My all time favorite.
