How do you get into The Hidden Tap?
We have not confirmed it. The Hidden Tap is in the directory because it described as hidden, and that is the whole of what we can stand behind about its door.
Drinks of the era
We have not seen this venue’s own list, so what follows is the period rather than the bar: Jack Rose, Diamondback, and Brown Derby are all drinks of this era, and each links to its origin and its build.
Where The Hidden Tap sits
Our record places The Hidden Tap in McHenry County, Illinois, in the Midwest of the United States. The source data carries coordinates and a county or region but no municipality, which usually means an address outside an incorporated city, or a record that was never given one. The map pin is the reliable part.
Illinois holds 71 listed venues in this directory. See them all on our Illinois speakeasy guide.

Prohibition in Illinois
Illinois came under national prohibition on 17 January 1920, when the Eighteenth Amendment took effect and the Volstead Act defined an intoxicating beverage as anything above one half of one per cent alcohol — a threshold strict enough to close breweries that had expected to survive.
