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)
Paperboy has a very cool and friendly atmosphere. You get fresh food and very delicious sandwiches! Perfect shop to have lunch after exploring the neighborhood.
