They have many vegan options. We eat vegan there regularly. After interrogating the staff, we came to understand that many items on the menu say "vegetarian", but the ones we've had were also vegan. They even have vegan "fish " sauce. I highly recommend this restaurant.

Pho actually refers to the noodles in the soup. And their menu does refer to the "Pho Soups" at the top/beginning of the section, then it lists the different varieties you can have under that..
