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)

Your typical brunch vibe, love the shakshuka. 

Vintage store with super good selection

A book shop with so many books that you can search for nothing but find anything. The owner is a member of the 70's french graphic design group Bazooka.

There is something moral to design things that will last for a very long time, for me it is important to visit the modernists. It is always stimulating and joyfull to visit the permanent collection of the Centre Pompidou.
