I think the best ones I had in Vietnam were on Cat Ba Island, in Ha Long Bay. They used used a sort rotisserie kebab to cook the pork, and added an egg. I found it really interesting how every region had its own way of making them. Before I went to Vietnam, I had this idea that there was a "proper" banh mi, but the only thing they all had in common was the bread roll.
