Yeah, I actually tried a similar place in Cambridge, MA about 5 or 6 years ago http://www.fire-ice.com/ and have only more recently seen discussion about this trend of Mongolian BBQ into which it seems to fit.

I have noticed that a lot of these places don't mention Mongolian BBQ at all, though, so it's not really surprising that you didn't connect the two if you haven't experienced such a place before.

As far as I know, this restaurant genre has still not yet reached the Pittsburgh area at all, although the rise of chains/franchises in the arena will probably change that. Someday.
