Went several times over about a year's time in 2012 and 2013, hoping to find something just right, but it didn't happen. I've had good Vietnamese food, but this isn't it. The food was either seriously over cooked, under cooked (raw), or old (smelled spoiled and stale), and the size of the portions (of the same dish) would vary radically from one visit to the next. The waiters were friendly the first couple of times, but after that, became waaay too friendly, giving me no personal space whatsoever. At one point during a slow afternoon, a waiter pulled up a chair next to where I was trying to eat, sat down, and proceeded to talk to me throughout my entire meal! I did not invite him, he was not a personal friend, nor did I want him there, but I didn't want to be rude. I was alone, so I guess he felt entitled since I never saw any of the waiters (all male) do that to anyone else. During later visits when I hinted that I wanted to be left alone (by taking out a book), they (3 different ones) became rude, pushy, and insistent. I will never go back. I'm a nice, quiet person who minds my own business, tips generously, and is always polite. I work long hours and eat out a lot. They lost a good customer.
And by the way, TripAdvisor, I visited about 15 times over at least a year's time, for lunch and dinner (the menu is the same for both). There was no "one" visit, and this is relevant to this review. Why don't you include the option under "when did you visit" of saying it was for several visits and not just one since patterns are a reliable way to judge something?
