I have not eaten at Teppen Edo, but I have heard many say that while it is good, it is pretty much identical to just about any hibatchi you'd go to at home. the chef will flip food into your mouth, light his hat on fire, and make a volcano out of an onion. While fun, is pretty common.
So not factual!!! If you have a Japanese Steakhouse you eat at near home you may want to consider Biergarden.
I have eaten and enjoyed both.
I would choose Teppan Edo
