My personal favourite night life spot is the Café en Seine. Admittedly, it's more of a café and restaurant during the day, but on Fridays and Saturdays starting at 10 p.m., it changes into a popular combination of pub and disco. It always gets crowded so it's a good idea to come early. You might be disappointed that the place closes down at 2:30 a.m., but until that time, the place is crazy. And even better: entrance is free.
