I had lunch there yesterday and they may challenge Pho-Cali for the best Vietnamese in the Triangle. Mind you, that's a lot like winning the Tallest Shortguy Award. Either would be lucky to crack the top 20 in any area that actually has a genuine Vietnamese food scene.
The Cha Gio (eggrolls were a bit cold and didn't come with enough lettuce and herbs to roll them up. That was probably the weak link.
The Pho was actually quite correct. The broth was clear and delicate, the various meaty bits were all edible, and the garnishing herbs were somewhat abundant (but not lavish). I was unable to say any of these things about the same dish at either Dalat or Lime and Basil.
My dining companion had the Bun with Roasted Pork and it seemed about right if a bit short on herbs and veggies.
We ordered a collection of sammys to go and they put all the marinated veggies and cilantro in a seperate ziplock bag. That was nice if you were planning to reheat them later. I found them to be good if not great. Certainly good enough to satisfy a fix without going to Greensboro.
Oh, as far a local, they're in that shopping center at Miami and Alexander that's filled with lunch spots. A note, despite the fact that nearly all the other places there are only open for lunch, they're open 9am to 9pm (hence 9n9).
