Cheesy Bean and Rice Burrito

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.

Spicy Potato Soft Taco

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.

Shredded Chicken Quesadilla Melt

A warm flour tortilla filled with shredded chicken, creamy chipotle sauce, melted 3-cheese blend and grilled to perfection.

Triple Layer Nachos

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.

Spicy Tostada

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.

    By far the worst taco bell in the area. Highly unprofessional, managers can never be found, Terrible wait time. The whole place needs improvements or needs to just close down completely. Not to mention they are always out of something. The restaurant is honestly just a circus at this point and i don’t see why they bother keeping it up.

    Order food last night they got it wrong and forgot stuff in the order I called up there five time they didn’t answer I contacted door dash they said it was Taco Bell call Taco Bell talk to the manager Tony. They said they could replace it and then when I got up there, there were two chicks yelling at me and telling me that I couldn’t replace it and when I told them that DoorDash says that it wasn’t on DoorDash that it was on them, they said that they were gonna replace it but they don’t do this and then next time I’m just out of luck we went up to the window. They didn’t. They barely looked at us, gave us really mean looks.

    I put in an order at the kiosk, I waited 20 or 30 mins, they call out other names I assume they'll call mine, finally I ask and they put mine up with the mobile orders and i couldn't see the receipt, when I did get my food it was ice cold, waste of money

    DO NOT GO HERE. THEY WILL WASTE YOUR ENTIRE LUNCH BREAK. This Taco Bell should be banned from accepting more than 6 orders at a time. You currently have a full restaurant and two people actually eating. 15 people waiting.... all have been waiting for at least 15 minutes... staff your stores worth a damn. An automatic order cancellation button should also be mandatory. You are holding people hostage. I cancelled my meal and will now get a refund in 30 days. I was literally just charged to sit in their lobby for 35 minutes. I could have went to a restaurant... sat down... drink a marg and eat my meal before Taco Bell could make a taco.
