So there’s cheesy, and then there’s cheesy. But how can you get to the good kind of cheesy? Like cheesy cheesy. Simple, take the Cheesy Bean and Rice Burrito for example. With a perfect combination of warm Nacho Cheese Sauce, refried beans and premium Latin rice all wrapped in a soft flour tortilla, it’s the kind of cheesy you definitely want.
If you’re one of those kids who has a thing for hot potatoes, why don’t you just try the Spicy Potato Soft Taco instead. It’s got warm and seasoned potato bites, melted real cheddar cheese, crisp lettuce, and chipotle sauce for a little extra kick.
Crispy chips, nacho cheese sauce, refried beans, and red sauce; you know that whomever you’re with is going to want “just one.” Before you know it, there’s one chip left: the chip at the bottom of the pile, with only a corner covered in cheese and a tiny pinto bean. So get a second Triple Layer Nachos for you and your friends.
We could all learn a little something from Spicy Tostada. Most meals try to keep everything hidden behind a thin layer of tortilla or corn shell. Spicy Tostada, on the other hand, has no insecurity about sharing its true inner self. It doesn’t care if you see its refried beans, real cheddar cheese, and lettuce. It doesn’t mind if you think its red sauce is maybe too red, or not red enough. Or if its chipotle sauce may be a little hard to pronounce.
If you’re living life the way you’re supposed to, morning is always going to be a struggle. This is why Mountain Dew® Kickstart™ exists, to give you the energy to fight through the fatigue.
Check this out: if you make good with the Brisk® guys who run the party, they might take you to this secret dance-club thing below the tree, and all the roots are actually straws filled with free Brisk® Mango Fiesta.
Instead of a crunchy corn shell, the Soft Taco Supreme® has a soft, flour tortilla. It’s so soft, it exclusively listens to Toronto hip-hop. Dreamy. Soft. Delicious.
A warm flour tortilla filled with tender shredded chicken, seasoned rice, avocado ranch sauce, and real cheddar cheese. In terms of wrapped meals, the Shredded Chicken Burrito is perfect.
Your choice of marinated and grilled chicken or steak served with guacamole, pico de gallo, black beans, crisp lettuce, seasoned rice and reduced-fat sour cream all packed into a seriously powerful bowl.
With its warm seasoned beef, nacho cheese sauce, crisp lettuce, diced tomatoes, and a crunchy tostada shell... one might say the Crunchwrap Supreme® set the rules for all Crunchwraps to follow.
A warm and melty quesadilla wrapped around seasoned beef, seasoned rice, cheese, nacho cheese sauce, reduced-fat sour cream and chipotle sauce grilled to perfection.
A warm soft flatbread layered with a three-cheese blend and warm nacho cheese sauce wrapped around a crunchy taco shell filled with seasoned beef, shredded cheese, shredded lettuce and spicy ranch sauce.
A soft flour tortilla filled with grilled, marinated all-white-meat chicken, a melty blend of three cheeses and creamy jalapeno sauce grilled to perfection.

Very unpleasant experience. The girl on the speaker (drive-thru) was speaking very fast and over me and basically rushing me. Once I got to the window it was the same female and it was the same feeling. I don't normally feel intimidated by people but she was rude and very short and quick to reply as she was when I was ordering. This was about 6:15 in the evening on a Monday.

Did mobile orders multiple times here to give them a chance, but they ALWAYS get orders wrong no matter who’s on shift.
One time they gave me a crunch wrap and burrito with NO MEAT and forgot BOTH my drinks! Insane!!! Go to any other Taco Bell and definitely not this one!
