Midnight's Café

In the 17th arrondissement of Paris, not far from the Monceau Park, a weird café lights up the street.
A few streets from there, another light is on, on the third floor of a building. Although it's becoming real late, Evelyn is too depressed to fall asleep.
To change her mood she decides to take a stroll in her neighbourhood. What will happen when she pushes the door of the small, weird café, a few streets afar?
