This is my old review so I thought I'd update it since this place is now closed due to a tragic incident that happened back in March 2013 - an employee was shot by her husband then he shot himself inside the restaurant. It was on the news: (http://www.abc15.com/dpp/news/region_southeast_valley/mesa/fd-shots-fired-at-mesa-business)
Anyways, they have a new location that's owned by one of the brothers. Its located on Dobson & S. of Broadway, behind Domino's Pizza: http://www.yelp.com/biz/pho-thuan-thanh-mesa
Be sure to order their Pho #22 with rice noodle. They use quality meat and you wont find anything weird like fish eyeballs in your soup. It consists of quality thin beef strips, fish meatball (don't let this freak you out...its good), pork wonton, shrimp, crab & squid.
My other favorite is their fresh spring rolls (not fried) that come with Hoisen & Peanut sauce...super cheap & healthy.
They also have another location owned by their sister. It's located on 19th Ave & Camelback (http://www.yelp.com/biz/da-v%C3%A0ng-phoenix-2)
