Like the holograms back at Headquarters. Most of the architecture is custom-built, but the entertainment is pretty much identical from what you'd find in rest of the city.

[ Miles had been given the tour (once during his first arrival, a second time once he'd... been given a proper welcome. The reception he should have gotten from the get-go.) It doesn't occur to Miguel that the Morales kid missed out on the granule of context that the Spider Society was his home dimension. Both the building and the expansive city outside of it.

It begs the question how on Earth Miguel had the resources to provide such a thing - but, there it was. Something about loneliness really drives a guy to set up a colossal spider-themed multiversal refuge. ]

It sounds like the Fifth Floor Library was too boring a location for your grand tour.
