Le dernier étage d'un parking transformé en jardins suspendu: lieu insolite, cadre très agréable aéré et lumineux, concerts, stands de bouffe, bars, petits endroits où se caler.

The very first place i've been in Paris.  My first month in the city, i spend over 800€ in this bar (true story) It's simple, warm and friendly, drinks are not so expensive (for Paris...). You can talk with every body, people there are open minded and funny (but only because everybody is drunk)
