Speakeasy in Paris...The Hidden Kitchen...Find your way there!

Prior to my visit to The Whisk and Ladle in Williamsburg (New York), I never stepped into a home that sometimes became a restaurant even though that day I was there only for a CoWorking session.
It reminded me of what a Speakeasy might have been back in the days of prohibition.  
I knew that such establishments existed in Italy and Asia.  
It just happens that The Whisk and Ladle has a cousin in Paris, The Hidden Kitchen.
