The sauce tastes like it's straight out of a jar, and has that ubiquitous shade of red found in Chinese restaurants unlike any color found in nature. I've never made it over on a Saturday, but Nam Son advertises a special cold spring roll, made with rice paper. In the corner of the small restaurant is a refrigerator stocked with juices and Vietnamese soft drinks. Among the selections are a sweet coconut beverage and an orange drink that tastes a lot like Fanta with added pulp. I recommend the homemade limeade, made fresh daily.
Servers are friendly and well-versed in the menu.
They are always willing to tell you their personal favorites. When business is slow, they sit and watch soap operas between customers, but during peak hours they deliver your food exceedingly quickly.
