This place is a few miles from the Las Vegas Strip... but well worth the drive. They are very clean and serve some of the best Vietnamese Food I've had! I recommend trying their #12 Pho, which includes tripe and beef flanks.
I find it funny that they are called Pho Saigon 8 and my the meal I ordered was $8.00!
Get here either early or late just not during regular dining times, since parking is limited.
