I typically give 5 stars for restaurants I would come back to and also recommend.
We ordered the Nem Nuong and the Bun Bo Hue. Growing up in SGV, not as much as OC but we still had a wide selection of authentic Vietnamese food.
However, after 7 years of living in Vegas, I have to say the Bun Bo Hue is so far one of the best I've had in town. SGV good? No... But definitely something I would come back for in Las Vegas.
$8.99 for a bowl of pho is actually quite hefty.. But considering the location being so close to the strip (usually higher price point) and the ingredients (lots of tender meat) it's acceptable.
