I've been here many times and I always tell myself that I will order something different but I always get their pho specialty there. I was very happy to find this restaurant since Phoenix is not known for their Asian culinary; however, Vietnamese seems to be one of the better Asian cuisines here in the valley.
I have tried Pho in L.A., San Diego, Chicago, Minneapolis, and Boston and found the best Pho broth here at Nam Sao. The rare beef could be a little more rare but everything else is perfect. Fresh vegetables (bean sprouts, mint, cilantro, lemon instead of lime) and the clear and savory broth makes their pho stand out.
