I am forever on a quest for great Vietnamese cuisine and find a lot of variety, some more ethnic than others, in the Dallas area. I have come to enjoy all of the postings in Chowhound, and trust all of the great tips on where to find the best, most ethnic places. However for Vietnamese, I have to look through tons of posts and I get side tracked. Could we start a thread that takes on Vietnamese only and could perhaps focus on restaurants in groups of speciality? Such as Pho, Bahn Mi, Truly authentic not Americanized, etc.
