Don't know how "authentic" this place is given the complete dearth of Asian beers, chopsticks, and Vietnamese accents in evidence. But I don't care. It is hands-down the best Asian food in the upstate, even rivalling some of the places I've been to on Atlanta's famed Buford Highway. We sampled the steamed pork and duck buns as apps and a grilled pork noodle dish (also called "Bun" just to make things confusing for us white folk) as well as a beefy Pho with all the trimmings. All uniformly excellent and flavorful. Excellent service by what I'm guessing are third generation Vietnamese-American kids (again, not a trace of accent). And though the atmosphere in this former fast food joint is a bit sterile, it is also immaculately neat and clean. I want a Bahn Mi...NOW!
P.S. Big up to Upstate Hound Danna for turning me on to this place.
