Just like the name suggests, each item on the menu features bacon, including a Bacon Soft Taco, which is like a regular Taco Bell Soft Taco but with bacon instead of seasoned ground beef. Specifically, it's lettuce, shredded cheese, and bacon nestled inside of a folded soft flour tortilla.
Here's the kicker though: Taco Bell actually offered a similar product here in the US back in the mid '90s. They called it the "BLT Soft Taco" and it was part of something called the "Sizzlin' Bacon Menu."
Beyond the Bacon Soft Taco, you'll find the Cheesy Bacon & Rice Burrito, Bacon Cheese Roll Up, Bacon Cheesy Fiesta Potatoes, and Bacon Cheese Quesadilla. Like the Bacon Soft Taco, they're simply normal Taco Bell menu items with bacon added.
