Denny's began as Denny's Donuts in Lakewood California in 1953, The plan was "To make the best cup of coffee; to give the best service; to keep everything spotless; to offer the best value, and to stay open 24 hours a day".

From that single donut shop evolved a chain of Coffee Shops serving sandwiches and hamburgers. Eventually the designation of 'Coffee Shops' was changed to 'Restaurant' and the name shortened to Denny's.
Denny's opened its doors in New Zealand in 1988 in Manukau City. Today there are currently 7 stores in New Zealand situated in Highland Park, Manukau City, Wairau Park, Auckland City and New Lynn in Auckland; Christchurch and Porirua, all owned by Rappongi Excursions Ltd. The Company plans to open more restaurants one at a time throughout New Zealand.
