My local in Saigon, 150m from my front door, charges 18k VND for an ice cold Heineken bottle (300+ml).
That's just a tad over $1 AUD, or let's say about 80 US cents.
When I go into town to watch sport at a sports bar I pay more, but at my favourite it is 35k for a Tiger draft pot (about 300ml). Delicious beer. Two bucks or less.
I can watch the game, drink 10 of those, eat a superb hamburger with chips, and come away with a bill of just over 20 USD.
May explain why I live here.
