In my opinion this is one of the best steak houses in Las Vegas. I've eaten at Old Homestead (Cesars Palace) and Bazzar Meats (SLS Hotel) multiple times but I just keep coming back to Jean Georges. If you like a few bottles of Moet with a perfectly cooked steak than this is the spot. No joke the seafood towers is great, the wedge is great, the steak is great, the desserts are perfect...it's a fantastic steak house and the atmosphere is perfect...very upscale and well appointed.
I've been coming to Vegas for over a decade and ever since the Aria opened this has been one of my favorite restaurants...give it a try.
