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)
There's a few secondhand clothes stores in Paris, but always immaculately selected, expensive and fashionable. Guerrisol however is a huge, dirt cheap jumble sale. Stock seems to rotate daily in each of their four stores, and prices fluctuate on the hour. Sifting through endless rails of synthetic jackets at €3 can suddenly reveal a hidden gem.
