I love going to Dom DeMarco's when I visit Las Vegas.  My friend that lives here always takes me when I come.  I usually get to choose the pizza, while she picks the Linguini and clams pasta, which is EXCELLENT.  I'd recommend going with that if you are sharing dishes between your party.  I've ordered the Big Apple pizza and it's pretty dang good.  Brick oven pizza is amazing and the quality is superb here.  It doesn't take too long to make either since the crust is so thin.  I've had it both with the NY and Sicilian style.  Although they're both good, I still prefer NY style.  Very tasty.
