Bia Hoi, most commonly found in Hanoi, is the most budget-friendly brew on the planet. Commonly described as having the appearance and flavor of Bud Light (go figure), Bia Hoi can be found for 3,000 VND per 12 oz. glass, which is the equivalent of about 16 US cents.
Gullible tourists and Vietnamese hobos seeking the beverage, need look no further than the ‘Bai Hoi’ or ‘Fresh Beer’ signs scattered throughout the city. Fresh beer is actually Bai Hoi’s English translation, and it is indeed brewed fresh daily — presumably in someone’s bathtub.
There's no definitive word yet on whether it is worth the price. Link -via the Presurfer
