The new Knowledge Graph layout that was rolled out last week is today displacing Business Knowledge Panels, but not for all businesses. Is this an April fools or part of wider bugs being reported with business pages disappearing from maps and local packs.
The Business Information has been removed from the Knowledge Panel and replaced with a Knowledge Graph. There is now a Map appearing within the organic result section. All details of website, reviews, summary description, reservation, booking information is no longer visible.
This is a bug with business pages. If you move the businesses PIN marker the information re-appears as normal. See Reports

Moving the PIN marker slightly, restores the information. Google My Business is working on the bug fix.
