The restaurant is constructed from two diners; the Country Girl Diner from Wilmington, Delaware, which was sold in order to clear the land for what is now I-95. The second diner came from Hares Corner, New Castle, Delaware; The Viking Diner.
The restaurant officially opened 21 June 1979.
In July of 1989 the addition of a dining room was added and the kitchen was tripled in size. The name ChesDel was chosen due to the restaurant’s general location, combining Chesapeake and Delaware to make ChesDel.
Located next to the ChesDel Restaurant and owned, currently, by the Lester family, is a historic landmark. Classified as such due to the architectural advancements and additions over the years. The house is from the 17th century and incorporates many different types of architecture from multiple periods, which is what makes it so special.
