By zooming in and clicking on it, Google literally blows the roof right off the building by allowing you to toggle through its various floors, making it easy to find things like bathrooms and stairs.

While the mapping feature is underutilized at the moment, don’t expect it to stay that way for long. https://www.google.com/maps/about/partners/indoormaps/ ... https://www.youtube.com/watch?v=6048zzMI8EM
