Bless.
I had an internship here in 2013, and had the most wonderful experience.
My favourite time of the day is when we have lunch on the little bench outside of the shop and passerby will shout out bon appetit. :)
I love the products from bless. Absolutely original and uncool :)
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)
