I haven't tried one yet but know it is one of those cult like McDonald's items that comes and goes. My favorite new addition had been the "Mac" snack wrap. Haven't had a "Big Mac" for years because I try to stay away from bread. I don't really remember seeing a commercial for it but had to pick up dinner one night in a rush over to one of my kid's activities. They had two for $3.18 so I figured I'd give it a try. It was heaven in a tortilla for me.
