Oh yeah, I ate at a few places like this in Cambodia but it wasn't as posh.
Sat at a plastic table and a plant pot with a mesh on top was placed next to your table and you were brought some plates of raw meats, salad and rice. It was fantastic
There is also a different 'BBQ' where there is a dome like metal object with lines in to let the heat and smoke through which you place you meat on and a with a shallow moat running around the bottom, you fill that with water and noodles and the juices that dribble down from the meat make a broth in the moat, the too is AWESOME
