The Wall Street Journal listed the following as current Paris Hotspots or “Les Hotspots”. Below is information on each place:

Paris Plage
A man made beach along the right bank near Notre Dame. Do not take a dip in the water lest you be swept out to sea. The currents of the Seine are nasty indeed. The Paris Plage gets very crowded in the summer time.

Mini Palais
Amazing food.
