Hi, my wife and I are meeting two out-of-town friends in Manhattan this Sunday. As we usually eat in Queens, we need your help. We would like to take them to a nice (preferably moderate or moderate/expensive in terms of price) Italian restaurant, with good food, ambiance, and a relatively quiet environment conducive to conversation. Mid-town or nearby would be the ideal location, but I would take recommendations for anywhere in Manhattan. Thanks in advance!
