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.
