What popular fast food chain encouraged customers to "Think Outside the Bun"?

• Taco Bell:Taco Bell has entertained fast-food lovers over the years with their catchy slogans such as “Yo Quiero Taco Bell,” “Think Outside the Bun," and "Live mas." Their slogan "Think Outside the Bun" is a play on the phrase "think outside the box," meaning be original and think differently. With the majority of Taco Bell's competition coming from fast-food restaurants that are known for serving hamburgers (McDonald's, Burger King, etc.), Taco Bell urges you to "think outside the (hamburger) bun" and indulge in their coveted Tex-Mex cuisine.
