This review is based on their pho. Being that I am a friend of one of the employees, I got a tour of how they make their pho. I posted three photos from the kitchen (grilling onions, ingredients, and simmering pot). They use an assortment of beef and beef bones with the ingredients in the pictures. They told me it takes about 12 hours of simmering to make the soup.
I have been to many pho places in LV and here in Colorado. It may be a subtle difference, but most pho places' soup base isn't as flavorful as the one I had at Pho Lan. After seeing how they make their soup base, I appreciate the food and their pho a lot more.
