Gross
This has an All-You-can-eat buffet of mounds of noodles, meat, vegetables of all kinds, and soup. Its not all that great, and just about none of it is recognizable as Mongolian cuisine, no dumplings, horse or mutton
They serve all kinds of random crap, including a fair bit of mexican food, your "mongolian grill" bowl can have salsa, sour cream, pico de gallo - since I presume thats what Americans expect from ethnic food. I observed a number of seriously fat people at the restaurant, who are obviously drawn in by the All-you-can-eat.
I'd be up for trying Khorkog, but I would not go back here.
