Get there early enough, and Hyde Bellagio is the perfect perch from which to watch a couple of rounds of the Fountains of Bellagio show while sipping on well-executed cocktails. Head over later, and that’s when the party gets started (and you may forget all about the fountains). Though it looks like an Italian villa on the inside, the lounge transforms into a serious nightlife destination, complete with ridiculous bottle service presentations (at one point you could pay tens of thousands of dollars to press the “button” that starts one of the Fountains’ performances). The lounge opens nightly at 5pm until 10pm, while the club opens at 10:30pm on Tuesday, Friday, and Saturday until 5am.
