We always visit Nora's when we come to Las Vegas. It is a nice alternative to something in the hotel and the food and service are always great.
I opted for the "Crazy Alfredo" on my last visit and it was decent. I still prefer their Vodka Penne over most of the pasta dishes there. The place has a decent selection of wines by the glass as well.
The antipasto salad is pretty good and plenty for two people to share as a starter.
