Even though Taco Bell's slogan is think outside the bun, the taco chain made a taco burger, bun and all. Customers were not intrigued by the ground-beef taco burger, and decided to stick to tacos at Taco Bell and burgers at other establishments. However, some customers miss the retired item; a small but loyal Facebook group, Taco Bell Please Bring Back The Bell Beefer, begs the taco chain to revive the product.
