Lao National Culture Hall
Lao National Culture Hall or Ho Watthanatham in Vientiane. I’ve never been inside this place but drove by a few times during my visit to Laos in January/February of 2007. It looks quite impressive from the outside, a modern building with a touch of Lao style.
Better hurry up and send me your Meal submission as time is running out. 
I really like the design when I first saw a picture of it.
