Not to be outdone, Taco Bell has been experimenting with its own waffle-based creations.

Taco Bell, a division of Yum Brands (YUM), rolled out a "Waffle Taco" last year, before switching to a "Biscuit Taco" in January.

The Mexican-style fast food chain sells three different combinations of sausage, egg and cheese awkwardly folded into a taco-shaped biscuit.
