Unlike the original Waffle Taco, the two new versions were/are offered as all-day options.
The Chicken & Waffle Taco featured a breaded chicken patty folded inside of a waffle taco shell (i.e. a folded waffle). It's served with a choice of either country gravy or syrup. The test price wast 99 cents, but I imagine a finalized price would fall between $1 and $2.
The Very Berry Waffle Taco is a waffle taco shell filled with whipped cream and fresh blueberries and strawberries. The test price is 79 cents per taco.
While the Waffle Taco incorporates standard breakfast staples, the Chicken & Waffle Taco embraces a recent trend of chicken and waffle items (see here, here, and here) and, along with the Very Berry Waffle Taco, offers a combination not currently offered by major competitors.
