Why eat "Italian" on the Strip when you can mosey over to a locals place? I've eaten at Nora's multiple times on multiple trips now - I am as big a fan as ever.
It's in a strip mall (what isn't in LV?) - and the decor is average. What kills it is the food. Their meatballs make me cry. The pasta isn't cooked until a toothless person can easily gum it - it is al dente like pasta is supposed to be.
The arancini (Rice Balls) is very tasty.
As others have noted, you will not leave here hungry. I am famous (infamous?) for being able to finish my food and any others' leftovers - not here.
I worked at a family owned checkered table cloth Italian place which has since closed - if I lived in LV, Nora's would definitely be at least a weekly ritual.
