I came here a few years ago. Pho tasted bland. Just came back recently because a bunch of people were going... still tasted the same bland flavor. Seems their broth just has no flavor kick to it. It's not terrible but there are better pho places out there in Tempe.
There's Pho Cao (good) and Khai Hoan (very good). Try those places in Tempe. Better pho places are even better in Mesa. Strong broth. Lots of meat.
