Pho So 1 is located in a strip mall about 2 doors down from 99 Ranch. It's quite popular with the lunchtime crowd - the one time I tried to dine in during lunch, I ended up having to share a table with 4 other people, none of whom appeared to know each other. Now I just order my food to carry out. Problem solved!
Food comes out very quickly. I'm a big fan of the bun cha gio (rice vermicelli with egg rolls), and the pho is delicious. The prices are definitely right as well - dinner for two, including appetizers and an avocado milkshake (my favorite!) for me, still came out to under $20. I will definitely go here again and again.
