4. The Monte-Carlo Casino
Monaco is a world gambling capital. Designed by Charles Garnier, the architect of the Paris Opera, the Monte-Carlo Casino regularly appears in Hollywood movies. It made an appearance in the 1995 James Bond movie GoldenEye, for instance. There is a €10 cover charge to enter, and the house requires formal attire. Once you’re in, it’s up to you how much you are willing to play.
