Diners, Drive-Ins and Dives is an American food television series that premiered in November 2006 on the Food Network. First produced by Page Productions and now by Citizen Pictures the program stars and is hosted by Guy Fieri. The show originally began as a one-off special, based on the idea proposed by David Page. When Food Network launched its HD simulcast of its SD channel on March 31, 2008, later episodes of the series began to be presented in high definition, although it never aired on the former Food Network HD channel. The show features a "road trip" concept, similar to Road Tasted, Giada's Weekend Getaways and $40 a Day. Fieri travels around North America looking for the best diners, drive-in restaurants, and dive bars.
