Swedish nightlife thrives in Stockholm, Gothenburg, and Malmö, although the scene is mainly limited to Friday and Saturday evenings. Swedes tend to stay at home during the week—particularly in the cooler months—and then go wild on the weekend. Nights out usually begin at a bar (just don't expect to find a perfect martini—due to the high cost of liquor, Sweden is very much a wine-or-beer country). Around midnight, there's a general exodus to nightclubs, many of which stay open until 5 am. You'll want to dress your best to fit in with the high-fashion crowd at the hottest clubs, particularly in Stockholm, but there are plenty of refreshingly unpretentious nightspots as well. There's also very little music snobbery—pop music is, after all, one of Sweden's greatest exports. (Everyone knows that the Swedes gave the world ABBA, but more recently Swedish songwriters have been churning out hits for stars such as Kelly Clarkson, Britney Spears, Madonna, and Kylie Minogue.) In the clubs, you might even hear schlager, the corniest of Euro pop. It's considered deeply unfashionable in much of Europe, but the Swedes love the stuff and cheerfully sing along.
