restaurant on north end of strip
You might try Stratta (Italian) in the Wynn. You could also look at the menu for Society Cafe at the Encore, I've enjoyed their breakfasts but haven't tried dinner there.
There are more options if you walk through the Wynn, cross the pedestrian bridge over to Palazzo- Table 10 by Emeril Lagasse, First Food &Bar, SushiSamba, and on the casino level- Dos Caminos.
