Nam Vietnamese Kitchen is "fast food pho" pit stop on 8th Street SW. Food is ordered at the counter and served to your table by staff. Probably best for lunch, or if you can't get to somewhere more authentic... for whatever reason that might be.
The menu is simple, the staff are nice, and the space was modern and clean. I stopped in at about 5-ish on a Sunday, which is likely not a peak time. It got busier after I arrived.
I ordered the beef salad rolls and the chicken satay soup. Both were fine.
