I've been to Little Saigon twice. Both times, my friends and I have got the exact same thing. Loads of spring rolls and the pho tai. The rolls are excellent, as other reviewers have noted. But for me, the highlight was the pho. The broth is so, so good. It can't but make you feel happy when you take a big slurp. Add some extra jalapenos on there, some sprouts and sauce and mmm...I need to stop writing this review. Making me hungry just thinking about it.
TIP: try the soda chanh mui (salted limeade with soda water) with the pho.
