I'm going to tell you a secret. It's not very often that I do this but here goes... This is one of my favourite wine bars in Paris. It's where I have celebrated my birthday (twice!), held my work-leaving party, come with friends, lovers, colleagues, even an ex once.
It's because it has a cool, relaxing vibe. You step inside and if you're lucky enough to find a free table, or intelligent enough to have reserved one in advance, you know that the whole evening is likely to pass by in a flash (unless you're with an ex, in which case, who knows!)
The lighting is dim, the colours bold, wines are available by the glass and the bottle. Special mention goes to the Mystery Wine ("vin mystere") in the oenomatic machine. The idea is that if you guess what the wine is (it has to be something on their wine list) you get the whole bottle for free. Always fun to have a pop.
It's not an extensive food range but what there is is absolutely delicious - prosciutto with truffles, a bowl of running burratta, beef tartare, and an exquisite tarte au chocolat or even the tarte au citron - and the menu changes often so you won't get bored. Highly recommended.
