1. Bellagio Patisserie
Akin to Willa Wonka for adults, the focus of super-chic Bellagio Pâtisserie is the globe’s biggest chocolate fountain. A winner of the Guinness World Record, this waterfall of wonder circulates practically two tons of chocolate and is 27 feet high. And while you're not allowed to swim in it, it will arouse your cravings for some of their other stuff.
