I have been eating at different Pho resturants since 1998. You know that super thirst you get after eating a bowl of yummy Pho? It's because of the MSGs. The Spring Roll Factory doesn't use MSG so no super thirst or after taste. The owner came and was explaining how he makes the broth everyday. I will have to say that it is the best Pho place in all of Arizona. I pretty much have discovered all the restaurants in the Valley....even the one up in Flagstaff, which isn't so great.
