Head for the seductive La Fiesta/Le Cotton Club, place de la Gare (tel. 03-89-23-43-04). Popular and busy, this nightclub consists of two strikingly different venues: On street level, La Fiesta is a bar with lots of suds, margaritas, and a busy after-work scene. Upstairs, there's a cocktail lounge with a dance floor and a calmer, more urban (think Paris or Berlin) ambience. For a mellow atmosphere, try the piano bar Louisiana Club, 3A rue Berthe-Molly (tel. 03-89-24-94-18), where you can groove to authentic blues and jazz.
