I'm usually not a big fan of buffets since it's all you can eat so they usually skimp out in quantity over quality. But Palace BBQ Buffet is great.
At one area there are heaps of raw meat, another, rice and soups, the third, a huge variety of kimchi and condiments, and another for misc. desserts, fruits, and other edibles.
You get the raw meat from the buffet grill it yourself on the hot metal surface at each table, suction domes on top of each surface suck up the greasy smoke.
It's pretty fun to cook your own food if you get to do it on a big metal surface...
