It is defined as a "place specializing in cocktails", and it really is... very particular, very good cocktails, both alcoholic and non-alcoholic.
We had an aperitif, very good. I recommend the meatballs and the "beef cheesecake" (it's a tartare).
The place was so nice that we couldn't leave; when we went out we bought the coasters, they were really nice.
Highly recommended, especially for an aperitif with friends.
Ps: there is gluten free food (and it's no small detail).
