The food scene in Vietnam is all about the masters of one - restaurants named after one dish, serving one dish. You’ll find places with “Bun Cha,” “Pho,” or “Bun Bo Nam Bo” in their name, and the only options you have are whether your Bun Cha comes with or without spring rolls, whether your Pho has rare or well done beef, whether you want Bun Bo Nam Bo or nothing. The only way for these people to stay in business is to make their one dish really well, so you can feel confident that you’re going to get an excellent meal.
