The first thing I would suggest is pho. In broadening my horizons some, I might suggest pho. And did I mention pho?

But in seriousness, I think pho is one of the great soups of the world. I've had it from restaurants here in NY to a small hole in the wall place in Hanoi, where it was mind bending good. Due to the ingredients, meat and such, and noodles, it's really a man course dish. Apart from pho, the banh mi, as mentioned, is often very good. I also like both the fried and steamed spring rolls. There is also a dish with cut up fried spring rolls on a bed of angel hair pasta that I love. Enjoy!
