Enter the lobby of the George V, avoid the flowers and turn right.
Not only an evening hang-out, Le Bar is also a modest and cosy space, open throughout the day. The expresso at a less modest 12 euros is served with mineral water and mini cookies. The bar personnel seems like they have been there forever and give personalized attention to each guest, engaging easily in conversation.
A good spot to meet with people, to see people and be seen.
