I can't say anything bad about Carmine's Little Italy. Like most places in Vegas, the architecture of the restaurant is strip mall inspired, which can make it less than inviting. But once you do go in, you won't be disappointed.
The place is huge. The centerpiece is the bar with h-d screens surrounding it from the top. The bartenders are fast and friendly. They'll bring your food right to the bar or you can grab a table in the huge dining area. For smokers, there's plenty of patio space to come and go as you please.
I didn't eat much when I visited. I had the fried mozzarella. Most places you'd expect the puny sticks a la TGI Friday's. But what you get for a similar price are three or four substantial diagonal shaped fried mozzarella pieces with plenty of marinara. It's just one of those little things that make you say hey, that's cool. The menu is extensive and the server I had was really busting his butt and friendly. I left a good tip.
If you're thinking of a night with a big group to see a game or just to get together and enjoy each other's company, go to Carmine's. It's located near the US 95 freeway for easy access. I need to go back soon.
