Out of all the Pho spots in the Southwest area, Rainbow/215, I'd choose Pho Saigon 8 rather than Jenni Pho or Pho Annie.
Main reasons is their fast and friendly customer service. The prices are reasonable. We've been here multiple times and they are prompt with serving water(s) while you take a look at what you want to order. Never have we felt rushed or impatiently waiting for service. The restaurant is large enough to cater to large groups. They have a couple big screen TV's around with the sports channel on. Go Knights Go!
My usual order is No. 11 (noodle with rare eye round) in a small. Broth is good. Can't forget to add Hoisin sauce and Siracha chili to give it some kick. The egg rolls are always a must.
No cash? Don't fret! They accept cards here. Not like another pho place I know, that was cash only (no bueno).
