Today’s version of Maxim’s a hundred years ago, i.e. the cool late-night place to see and be seen and have a good time is Le Baron. It attracts hip Parisians and international celebs but is at it’s best during fashion weeks when models and designers and photographers improve the fabulous factor by ten.

It’s been called Paris’ version of Studio 54, and ever since Le Montana opened in spring 2009, the private club has been where anyone who is anyone wants to be out late at night. Designer Vincent Darré laid a sexy decor over the historic bones of one of St. Germain’s legendary watering holes and during fashion week, the atmosphere goes mega-beautiful with masses of models and those that follow in their wake. You may catch a glimpse of Marc Jacobs, Kate Moss or Grace Jones; you will definitely witness revelers having a seriously good time.

The first discotheque to open in the center of town for a long time, ParisParis has taken off by attracting a sophisticated crowd with a combination of hip dance music and stylish bordeaux-and-black decor. If dancing is what you’re looking for, it’s better to go during the week (on the weekends the Parisian crowd is thinned out by suburban hordes). On the first Monday of every month, the famous boutique Colette hosts a dance class here. Closed Sunday and most Mondays. Métro: Pyramides or Palais Royal-Musée du Louvre.

The hottest new club in Paris also has an unusual venue—occupying around 20,000 square feet beneath the stone arches of the Right Bank approach to the Pont Alexandre III. These lit arches give Le Showcase a warm ambiance, including, away from the dance floor, several quiet areas furnished with black leather seating. The program changes regularly: some nights a DJ spins; on others, there are live performances or special events, but the client list includes a diverse mix of chic Parisian night owls as well as recognizable names like Nicholas Sarkozy. Open Friday and Saturday, 10 p.m. to 6 a.m., and Sunday brunch.
