It's part of Caesars Palace, located right across from the main entrance to the hotel.
This is Gordon Ramsay's fifth restaurant in Las Vegas, and it extends his partnership with Caesars Entertainment. Walk out the doors of the hotel's main entrance at 3570 S Las Vegas Boulevard, and you'll see the towering building with a sign that reads "Gordon Ramsay's Hell's Kitchen" (it's got the bronze pitchfork straight from the set of the show; you really can't miss it). The new restaurant takes the place of Serendipity 3, which closed in Jan. 2017. You don't have to be a guest at Caesars Palace to access the hotel or any of its restaurants — just walk right in . . . if you can.
