Guess where and how this picture was taken...

I promise to buy a drink for the winner of his/her choice!
Well, Don Perignon is an exception :) And yeah, people who have already been there should keep silence :))) Each person has only one attempt :) In case there are several winners I’ll buy a drink to all of them :) I’ll share the right answer as soon as you give your versions :) I’ll screen your answers so that you are not misleaded with someone else’s guesses :)
