So we've already taken a look at two "City within a city" areas so far - Roppongi Hills and Tokyo Midtown. Went to another one just outside Tokyo Station called Shin Marunouchi Building - a building indeed it is but a city lies within.
BTW, this image is in the wallpaper pool together with the Gurren photo of Yoko that you asked for ^^
BTW2, I'm going to be deleting images from the wallpaper pool soon so get them while you can.
I've never been to a place in Japan where there are so many chairs about the place. Was trying to figure out their strategy all evening ^^;
There are many little corners with chairs and I'm guessing that they welcome people to come to relax or have little meetings - and then spend money at the restaurants on the way out.
