Thrillist says the only thing better than drinking a cold beer in a foreign land is drinking a six-pack for less than a fiver. And there are destinations across the globe where a big night's bar tab can be covered by the coins in your pocket.
According to Thrillist, in Vietnam the average price for a pint is US$0.76. It reports that “What you'll be drinking: Almost assuredly Bia Hoi, on ice. While US$0.76 a pint is the average, it's pretty common to find a 12oz glass of this 3% ABV pale lager for as little as US$0.20 cents. For the bottled alternative, go with the Hanoi Beer. Pair it with: Assuming you've had your fill of Pho (rice noodle with beef or chicken), and Banh mi (bread), and try a glass with Ca kho to (catfish cooked in a clay pot).”
Also mentioned on the list of cheapest beer are Cambodia, Ukraine, the Philippines and Ethiopia.
