This is one of the places on my list of favorites when I'm visiting Las Vegas. It has a very family friendly atmosphere. We are usually in a large group and get good service. The pizza and house salad are the favorites for us. Both are large enough to share among a few people.
They have several promotions going on daily to save money which is always a plus. When we were there it was Disney weekend. If you had on Disney attire or dressed as a character, you received 25% off your bill. You can also get a free spin on the wheel of prizes for every large pizza you order. We didn't win anything there, but the kids thought it was fun.
Would definitely recommend going to Metro Pizza.
