Multiplexes in Tokyo

[drainer at mpinet.net]

I am looking for an American style movie theater in Tokyo -- huge screen,
big seats, digital projection, THX, etc...
Sometimes such things are necessary.
I can't think of a place other than the AMC at Ikspiari, or perhaps Virgin
Cinemas at Roppongi Hills (although I have never been there).

Any suggestions?
Tokyo 23-ku or western Chiba would be best, as Yokohama is a bit far.

Cordially,
