Where can I find BBQ Japanese/Korean buffet in Bangkok?

There's an all-you-can-eat Japanese buffet called Shabu Shi that serves sushi, suki and tempura in a few locations in Bangkok. It's pretty good for the price and includes dessert and soft drinks. I know there's one in the Central World Plaza Mall and one in the Esplanade Mall. I think the price was around 229 baht plus service charge. There's a Korean BBQ buffet at the Pathumwan Princess Hotel, and there's lots of other Korean bbq's and restaurants all over Bangkok. There may be one, but I've never seen a Korean/Japanese bbq buffet.
