http://news.ninemsn.com.au/article.aspx?id=625057 I've had a couple of these. I had one last year in the states at burger king. They're really not that big. They're a small diameter burger and probably have just as much meat as a double quarter pounder. Also, they're delicious minus the bacon and with ketchup instead of bbq sauce of course. I'm thinking of taking the double-quad stacker challenge tomorrow. How has everyone else been enjoying their stackers?
