Brasa Grill Steakhouse
An awesome Brazilian Steakhouse (all you can eat meat carved at your table) with a full buffet of "sides." Pretty expensive ($35), but well worth it for those with big appetites.
Sounds like a take off of Fogo de Chão
I love these places but although they are AYCE, I don't see them as buffets, which are AYCE where you serve yourself.
For American: Old Country Buffet
For Chinese: Grand Buffet
For Sushi: Todai
For Mexican: mi Pueblo
