Good food in Tokyo

Does anyone know of any great restaurants to get shabu shabu, Kobe steak, looking for any recommendations for some great food. Thanks.

A restaurant called 511 in Akasaka is my favorite spot for Kobe beef: http://bento.com/rev/3789.html

Banyou in Nishi-Shinjuku has good shabu-shabu, although I prefer their sukiyaki: http://bento.com/rev/1021.html

a) A511.jp is very tasty menu. Much creativity in how the chef presents tiny strips of kobe. It is well worth the money (15-20,000 Yen)

b) however, the ultimate in Kobe beef experience, will always be the 400 gram 2 month aged waygu that is char broiled in the oven at dons de la nature http://dons-nature.jp/ the magic that comes out of that oven has to be experienced.. defies all description.

c) although i didn't get there on my last vist

i read nothing but good things about Satou being a place to sample some of the other regional wagyu's.

Asakusa Imahan in Asakusa is a very famous restaurant for shabu shabu or sukiyaki.
