What is Wendy's fast food?

Wendy's is an American international fast food restaurant chain founded by Dave Thomas on November 15, 1969, in Columbus, Ohio, United States. The company moved its headquarters to Dublin, Ohio, on January 29, 2006. As of 2016, Wendy's was the world's third largest hamburger fast food chain with 6,500+ locations, following Burger King and McDonald's. Wendy's menu consists primarily of hamburgers, chicken sandwiches, French fries and beverages, including the signature Frosty, which is a soft-serve frozen dairy dessert.

Since phasing out their famous "Big Classic", the company does not have a signature sandwich, such as the Burger King Whopper or the McDonald's Big Mac - although, by default, the "signature sandwich" spot seems to have been filled by Dave's 1/4 lb. Single (introduced in 2011 as Dave's Hot 'N Juicy as a reworking of the longstanding Wendy's Single, shortened to simply Dave's in 2016), a square-pattied burger made with fresh ground beef rather than round frozen patties.
