Pho Bac is on Buford Highway in the same shopping center as Little Hot Pot. It's a pretty big Vietnamese noodle shop. Like most of these places, it's all business, no atmosphere.
I had the brisket soup. The broth was quite hearty. The side salad includes a leaf that doesn't look like mint but certainly tastes minty; I wish I knew what it was called. I'm still not sure exactly how to rank the various pho spots in town, but I did enjoy Pho Bac. And, in general, I think that pho makes a great lunch---well balanced but not too heavy.
