Beautiful independant Cinema recently restaured hiding a rooftop bar.
If you ask nicely you can access the bar without having to buy a ticket to movie and enjoy the view on one of the most dynamic avenues of the city.
Mosaic lovers will enjoy.
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)
