Denny’s is a full-service coffee shop/family restaurant chain. It operates over 1,500 restaurants in the United States (including Puerto Rico), Canada, Curaçao, Costa Rica, Honduras, Jamaica, Japan (transliterated as デニーズ Denīzu), Mexico, New Zealand, Qatar, and the United Arab Emirates.
Denny’s is known for always being open, serving breakfast, lunch, dinner, and dessert around the clock. Many of their restaurants are located in proximity to freeway exits, bars and in service areas. Unlike many other restaurant chains, Denny’s does not close on holidays or nights, except where required by law.
Denny’s was founded under the name Danny’s Donuts in 1953 by Richard Jezak and Harold Butler in Lakewood, California. They expanded to 20 restaurants by 1959, when the chain was renamed Denny’s to avoid confusion with another chain, “Doughnut Dan’s”. The business continued to grow and by 1981, there were over 1,000 restaurants in all 50 U.S. states. In 1977, Denny’s introduced the still-popular Grand Slam breakfast. In 1994, Denny’s became the largest corporate sponsor of Save the Children, a national charity. All but six Denny’s closed for the first time ever on Christmas 1988; many of the restaurants were built without locks, and some which had been reported having lost their keys.
