Been twice now. We are Pho-natics and have been to many Vietnamese places in Phoenix. Although not as good as Pho Trahn overall, this place is far better than most. What distinguishes it: service is very good, something that many Vietnamese places lack. Very clean, and has a relaxing patio (beware, they frequently have the patio closed however during the "cold" moths) and the ingredients they use are much higher quality. If you've been turns off by the fatty, low quality cuts used in Pho in other places, this is your place.
Also, while the Pho gets the most attention (Pho Bien and the pork/beef are excellent) the Hot Pot (K got the seafood) Soup was amazing. Very generous portion and almost sweet to the taste with a good amount of acidity. The Pho is very balanced in its broth but the hot pot is delicious if you're looking for something different.
