I've had the pho which I found to be underwhelming - the broth lacked that thoroughly savory quality you'll find in pho outside of DC. It was edible and they didn't skimp on the typical offerings - bean sprouts, basil, lime - so you won't find yourself pushing away the bowl.
Bottom line? It'll sate your craving temporarily if you can't get out of the city and happen to be on the Hill.
