Basically you have:
Yakatori House - Fast Food place opposite the main building in the bonzai garden
Tokyo Dining - Which I think is the more expensive of the two table service
Teppan Edo - Which is the cheaper one the table service. This is basically how Teppanyaki used to be with the tables of 8 around a hot plate and the chefs coming out to serve I believe (haven't been there since the change but this is the impression I got)
