I have been to Viet Bistro many times as it is the closest Pho in the northwest. I prefer a few of the Pho restaurants in China Town but for days when I am too tired to drive there this is where we go. It is for the most part as good as any Pho, broth is flavorful, decent sized. The Satay has great flavor but it definetely spicy. I have also ordered the Bun before which is also good, what is to be expected. We normally get the spring rolls too which comes with a peanut sauce, again good but nothing outstanding. I prefer my peanut sauce a little thicker but at least the peanut flavor is good.
The two things I don't like about this place is it is a $1 or $2 more than other Pho restaurants and it is right next door to a Cigar shop, the smell of Cigars (which I like in certain settings but not with food) seeps into the restaurant. I think the smell must come from the ventilation because there is no way that much just comes in from the outside.
So bottom line if you are looking for decent Pho in the northwest then this is the place to go.
