Nam-Viet is a Vietnamese restaurant that has quite an unassuming storefront in Cleveland Park. It is quite easy to pass by considering there are other restaurants with fancy fronts on the opposite side of the street. However, this place has some of the most amazing Vietnamese food I have ever had and for a very reasonable price.
The restaurant is not usually very crowded, which makes it easy to get seated and get your order in when you only have a 1 hour lunch break. The servers are very knowledgeable and have no problem making recommendations since it is traditional Vietnamese food, not just Pho. I found that their Pho Xao (#61 on their menu) to be my favorite because it is like a Vietnamese Pad Thai with meat and seafood. The dish is served with a vinegar sauce on the side and there is homemade Sriracha on the table. Both I found to be almost worth drinking.
