This was earlier this year in Paris : this was a promotional event organized by the Whiskey maker Jack Daniels. It took place near la Bastille in the Door Studios on rue Lesdiguières in the 4th arrondissement and it seems that lots of Paris-nights people were there.
At the door, the security detail was strict to make sure all incoming people were invited guests, not brawling youths looking for cheap fun. After leaving your coat, your helmet or whatever you needed to get rid of, you were given three plastic cards, each being a token for a free Jack Daniel's drink at one of the two stands. The motto of the evening was vaguely Warholesque, from the reproduction on the walls to the fancy disguise of several of the guests, beginning with Nicolas Ullmann who wore a magnificent Warhol wig. Nicolas Ullmann is from what I understand an active person of the Paris night scene. The guests, who were mostly twentiers and thirtiers with quite a good number of middle-aged men and women, were treated with hotdogs, pocorn and of course whiskey, served straight (if you asked) or in the form of cocktails.
