Not sure I'm buying into orders of magnitude of people visiting a "60's cafe in Paris". Just who, for example, is going to design said cafe that few people alive (You'd have to be 65+ years old, and that's being very generous) even remember? Don't see that use case gaining a traction so massive. What you described seems to be more of a Mind Machine Interface variety than a VR one.
