Just wanted to note that I had a phenomenal #1 (Classic) bahn mi sandwich today for lunch at Ba Xuyen. Thanks to Chowhound for the recommendation. It is well worth the trip and they are tremendously friendly there. I also had two of the small, pork/cabbage spring rolls that you grab with tongs from a hotbox (pretty tasty) and the intriguing pickled lemonade (probably wouldn't get this again--it is incredibly tart). I was impressed with the size of the sandwich and the baguette, which was perfectly crispy/chewy. I just wish I lived closer.
