US burger giant McDonald's has opened a mega-restaurant in Columbus, Ohio in a bid to ramp up its family-friendly image. The format boasts a dessert stand with coffee imported from Italy, and a living room area targeting adults. It also offers a karaoke booth for teenagers and a miniature drive-thru McDonald's for younger children, in bid to offer 'something for everyone'. A merchandise area offers consumers the chance to buy McDonald's gifts and clothing.
