I love pho, so when I came to Columbia, Maryland from Seattle last January, it wasn't long before I was searching for good Pho restaurants. Long story, but I've tried close to 10 of them and Pho Nam is the best.
I have been there seven times now and they have been very consistant with their soup serving me great pho each visit. The broth is wonderful which is the most important part of a good bowl of Pho in my opinion. The noodles are cooked right every time and the meat is thinly sliced. I order #15.
Also, their iced coffee and desserts are very good and reasonably priced.
The only downside is the dirty walls but the service is good and fast. If you need a "pho fix", go to Pho Nam and you'll be happy.
