This place is legit and won't hurt the wallet. We stumbled upon it on our way back to our Airbnb after a long day of softball and Rocco's is a godsend. The large meatball sub was amazing and huge (14" is actually a LOAF of French bread). Aside from the generous portion (could have fed 3 people), the meatballs were among the best I've ever had and I make damn good meatballs myself. The lasagna was tasty. Garlic knots are spot on. Eggplant was good. We didn't get to the Stromboli because we filled up on everything else (oops), but I suspect it will be good tomorrow.
We also picked up some rainbow cookies with marzipan, and Italian wedding cookies. Both were delicious.
The service was spectacular. We were exhausted and decided to order the food to go, and the women behind the counter walked us through the menu and made recommendations. Then they gave us some complimentary pastries to remember them by.
5 stars for combined tastiness, price point, and service. TL;DR: if I lived in Vegas I'd be a regular. Bravo!
