You cannot go into any of the buildings unless if you get registered as a visitor. If you are able to go inside the buildings, it s really amazing. They have displays in their workspace for people to use. These include 360 Google Maps, Chromebook displays, special artwork, Google history/infographics, and much more. If you aren t able to get inside, they have other things to look at too, such as the Android sculptures, volleyball courts, and more. They also have an arcade.
