We've been here twice now in the past month since we moved from NY. Makes us feel a little closer to home when we go. :-) The Rice Balls really took us back and the Lasagna Explosions (something we'd never even heard of before) were explosively delicious.
So far everything we've had has been very good (including the pizza we took home on our first visit) and very authentic (ie: huge portions). The garlic knots are OUT OF THIS WORLD - I mean absolutely phenomenal.
Staff is VERY friendly and will literally HAUNT you if your glass if 1/2 full for a refill (that is NOT a complaint either). They also push you for more garlic knots! Which is unbelievable to us because how am I supposed to eat any of this food when I have an endless basket of Garlic Knots in front of me? o.O
Edited to add: The reason I give them 4 stars and not 5 is because literally every dish (aside from pizza or a salad) is "over pasta" - it's kind of annoying. Basically, do not go here unless you're in the mood for pasta (or pizza - which is also very good). We do eat here at least a few times a month and I have to say, they have the BEST sausage in Las Vegas!!
