Pho Kim is AWESOME! Seriously one of my top 2 Asian restaurants in the Pittsburgh area. If you o, be sure to try the Pho. If you are adventurous, don't be shy to try one with beef balls and tripe. If not, go with something a little more basic. Either way, you get the same great broth and delicious taste.
Also, if you are looking for a starter, the fresh spring rolls are a favorite along with the Catching Fire roll. The Catching Fire is a sushi roll loaded with goodness and topped with jalapenos for the "fire". Taro bubble tea tops off any meal here or you can BYOB for a very minimal fee.
