The Dinosaurs from Roppongi Hills

Do you like dinosaurs? If yes, and if you're in Tokyo, you can admire a series of statues representing 23 dinosaur species.
I discovered this expo, called The Dawn of the Dinosaurs - Dinosaur Museum in the Skies when I went to admire Tokyo from Roppongi Hills. It will be opened until September 26 and it really is "in the skies", because it is located at 250 meters above ground, at the Mori Art Gallery, in the Roppongi Hills observatory.
If you don't care much for dinosaurs, you can just go to see Tokyo from above. :)
