Which of these fast-food chains is NOT mainly known to sell pizza?

The story behind the answer

Wendy’s is the correct answer because it’s primarily a hamburger chain—famous for square beef patties, Frosty desserts, chili, and baked potatoes—while Papa John’s, Little Caesars, and Domino’s are major pizza-focused brands centered on delivery and carryout.

Context tip: The U.S. “big three” pizza chains (Domino’s, Pizza Hut, Papa John’s; with Little Caesars also huge) built logistics around dough, ovens, and delivery speed. Wendy’s, founded by Dave Thomas in 1969, built its identity around made-to-order burgers and quick-service sides. Memory aid: Three names scream pizza operations; the outlier is the one known for square burgers—Wendy’s.
