Vietnamese buffet near Champs in Burnsville?
There's a very decent Vietnamese _restaurant_ across the street from Champps called Cam Ranh Bay, but it's not a buffet. The food is pretty good if you don't want to drive to some of the more downtown Vietnamese places. And they're nearing completion of a nice (and needed) remodel.
I don't know of a Vietnamese buffet near there. Nha Sang, which is a few miles northeast of there, has a nice - small, but very tasty - lunch buffet, but not Vietnamese - it's Tibetan and Chinese.
