" Bia Hoi One of the great pleasures of travelling in Vietnam, bia hoi – fresh draught beer – is brewed daily, without additives or preservatives, to be drunk within hours. Incredibly cheap and widely available, bia hoi is said to have been introduced to Hanoi by Czech brewers over 40 years ago. Every town has a bia hoi place, often with a street terrace, offering a very local experience. Park (or attempt to park) your rear on one of the tiny plastic stools and get stuck in. Snacks to eat are often sold too. "
