Actually they do have takeout.
My wife lets me go to Vegas alone, although ever since I retired I suspect she welcomes some time with me out of the house. She saw an article that mentioned the nutella-stuffed beignets and asked that I bring some home to LA. So on my last night I called in a double order of them, drove to the Wynn, valet parked, picked them up, and was back in my hotel in no time. The yummy donuts come with a cream dipping sauce, which I kept on ice for the trip home. Of course she loved them.
The hostess was very helpful and charming. The restaurant looked really nice - I think I'll try it on my next visit.
