Pho is naturally gluten free, so we had no problem here. The fun part was when we didn't recognize one of the vegetables. The server didn't know the English equivalent, so he typed the Vietnamese term into Google Translate on my phone - ngò gai. Turns out that it was coriander, and my wife loved it! Fun times here, and I didn't get glutened.
