In December 2014 I can now confirm there are at least four night markets in Vientiane!
The above three are all operating, though the one at Van Thong Plaza is much smaller than last year and has the kiddie attractions but not much food. I'm under the impression that most of the food has moved to the night market at Ban Anou, though I'm not sure whether this is permanent or happens each tourist season.
The big touristy night market with not much in the way of street food is of course still there each night on the river bank.
The fourth night market I found was on a corner of a main road right near Pha That Luang, the major landmark of Vientiane, but seemed very local and we spotted no other tourists. The food there was great!
Having found that last one I would not be surprised if there are other local night markets in other non-touristy corners of the city.
