The sublime Casino Baden-Baden (casino-baden-baden.de; adult €5) seeks to emulate – indeed, outdo – the gilded, chandelier-lit splendor of Versailles. Marlene Dietrich called it "the most beautiful casino in the world." Gents must wear a jacket and tie. If you’re not much of a gambler and want to simply marvel at the opulence, hook onto a 40-minute guided tour.
Under the same roof is super-stylish restaurant The Grill and upscale club Bernstein, where the dance floor heaves with beautiful people.
