What's to say that hasn't already been said?! This is as good as it gets for Italian food AND atmosphere in Las Vegas.
Needing an excellent date place? You can't go wrong with Grade-A Italian food and a friendly guy in a suit singing Frank Sinatra!
My only food-specific recommendation is the bruschetta appetizer. It's a must-order, and I could easily make an entire meal out of it.
Two final thoughts...warnings, really.
1) Yes, it's dark inside. It's very dimly lit, but I personally felt it added to the ambiance.
2) You're going to overeat on this amazing food and need to roll yourself out the door!
