I didn’t discover this "secret" pho place by accident – though I wish I did or at least could get away by saying that (that would have been more dramatic, isn't it?) – but rather, an article at Saveur pointed me to this pho stall at an upstairs apartment inside a run-down building in Hanoi’s Old Quarter. I was able to find the place easily, thanks to the article with detailed directions and pictures of the street signs, and arrived at the right time too, between 3-7:30pm as that’s the only time the place was open for business.
