Carl's Jr. is the restaurant that inspired the list. Two major reasons it's on the list:
1) Their TV commercials, which more often than not I find offensive and which never create any kind of desire on my part to visit Carl's Jr.
2) After several visits in the last year or so the food has been so poor tasting and so poorly prepared that they are the inaugural member of the list.
Technically they were put on the list in 2006, so my next visit will be sometime in 2012.
