It seems like pho vistro is hopping on the "healthy/organic" vibe as they have a vegan option and no MSG. BUT if you're use to eating traditional pho, this place won't be for you: broth is bland, one size only and no tripe/beef ball available.
That being said, the place is very clean and nice decor. The lunch special includes pho, spring roll and a drink for about $13. Not a bad deal as spring rolls and drinks by themselves are $3-4. Saving grace was the Viet coffee I ordered which was a nice finish to the meal.
