Just saw this and thought it's worth a post to say that I totally agree, you cannot beat Lao Beer for quality, and price in this part of the world.
If you can get it, well make sure you give it a try.
When in Laos on business its probably the only thing I drink, I'm not normally known for having a beer at lunch, but when in Laos, its hard to pass up. But then there's the French resto's in Vien Tien and the French wines at obscene prices.
A place to put on your list to visit!
