What is a speakeasy bar? Discover the experience at L'Univers Café in Nantes
Coming out of a show at the Théâtre de Poche Graslin, a film at the Katorza or simply walking through the centre of Nantes? Looking for a place that stands out? Speakeasy bars appeal to anyone seeking a more intimate experience than a regular cocktail bar. But what exactly is a speakeasy? Let us take you inside this world inspired by American Prohibition.
What is a speakeasy bar?
A speakeasy bar is an establishment inspired by American clandestine bars that appeared during Prohibition, between 1920 and 1933. At the time, alcohol was banned in the United States. Guests entered these discreet venues through a hidden door, sometimes after giving a password.
The term « speak easy », meaning « speak softly », referred to the discretion needed to avoid attracting the authorities. Today, the speakeasy keeps that spirit: an intimate atmosphere, a curated décor, creative cocktails and the pleasure of discovering a confidential place.
Why L'Univers Café is the speakeasy of the Graslin district
