Jean-Georges Vongerichten's Aria steakhouse has run since the property's 2010 opening — JG's signature steakhouse spec built into Aria's contemporary fine-dining frame, with property-level kitchen attribution kept at the concept tier (no current public-facing property EC). The kitchen runs Vongerichten-spec prime cuts alongside the chef's signature non-steak hits (the salmon, the rigatoni in spicy lobster broth, the tarte flambée Alsacienne). The room is Adam Tihany-designed for Aria's CityCenter sophistication; the program runs JG-disciplined without the JG-NY price point. For Aria's JG-signature steakhouse — chef-pedigree concept oversight without property-level chef-cult framing.
