MATTOON, Ill. (KTVI) – Burger King, one of the nation’s most recognized fast-food chains and home of the iconic Whopper burger, can use its name almost anywhere in the United States. That is, except in one small, specific part of central Illinois.

This rare exception stems from a long-standing trademark dispute with a small, family-run restaurant in Mattoon, Illinois, which for much of its existence has also been named “Burger King.”
