I have had Vietnamese food in Boston, DC, SF, Chicago, and Pittsburgh. The Pho here is certainly on a par with the other places that I have sampled. What sets Tram's apart for me are 2 things. 1. The spicy prawn is really different. I am not sure what it is that gives it its unique flavor and appeal but I have never had anything like it. 2. The spring rolls are absolutely amazing. I know that the spring rolls should technically be very basic--the ingredients are generally well understood etc, there are no real secrets etc. For whatever reason, these are the best springs I have ever had.
