What should White Balance for this be?

Posted in a Canon forum first as this photo was taken with a Canon point-and-shoot in 2006, but I have been using Nikon DSLRs since later that year, a D50 and now a D7000... feels like this is my "home" forum. Question is... what would be best white balance for this photo? At the time, it was in auto white balance setting, but I wonder if it should have been tungsten for the exterior lights or something else. Opinions? Advice?
