What were you doing last weekend? If the answer is anything besides checking out Vegas’ newest club OMNIA, you weren’t really living. OMNIA has uploaded an entire album of photos from its opening weekend highly capable of inducing postmortem FOMO. Four straight nights of debauchery christened the new nightclub at Caesars Palace and all the stars came out to play. Calvin Harris kicked things off on Thursday and Friday night before Martin Garrix brought down the house for Justin Bieber’s 21st birthday on Saturday. None other than Sebastian Ingrosso joined Martin for a b2b set that went until 4:30am. On Sunday, Dutch superstar Chuckie capped off the weekend, but it was really only the beginning. As these pictures clearly illustrate, OMNIA is an incredible, over-the-top venue unlike anything else around. You can excuse us while we fear and loathe ourselves to Las Vegas right about now. Check out the images below and head over to OMNIA’s Facebook for the full gallery.
