There are two Vietnamese restaurants on opposite sides of the Strip District and I definitely think that Pho Van wins out. We have been here about half a dozen times in the past few months and will continue to go back. Nothing fancy about it, but the food is good, the service is quick and the prices are reasonable. I ordered the curry chicken which had good spice and the chicken was cooked well - not gummy. The vegetable summer rolls and the shrimp summer rolls are great and don't fall apart when you eat them!
The portions are manageable but if you order a few appetizers, you may have some left overs. The other day I asked for my soup to go and didn't realize how much was leftover, but I ended up walking out with a quart filled with pho.
