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.

I went to order two taco Supremes and the guy told me that they were closed. It was 8:00 p.m. On a Monday evening. He told me I had to either order online or through doordash. So I asked him why can't they make the food if they are in the restaurant answering me at the drive-thru. I will say the young man was very polite but I still don't understand why they were closed and could not make my tacos. I do not recommend this location

Genuinely the worst Taco Bell location. I work by the one in the valley and that location always gets my order right, always great service, and you get exactly what you pay for.
This location is terrible. Our orders are frequently wrong. They skimp on ingredients. Rice is sometimes crunchy. And the staff is rude. I ordered something I’ve gotten at this location previously and they acted like I was crazy and said they’ve never had that item. I’ve even literally read items off their menu board for them to act like I’m insane and say they don’t have it.
The fact that they also have the single worst drive-thru exit in the world is just the icing on the cake.

This used to be one of the best around. The past few times it has been terrible. Paid $10 for the wrong burrito and old fries. They also tried to keep my change. When I let them know that I needed my money, they acted like I was inconveniencing them. Terrible service.

Went there around 12:30 a.m. after work. Let me get in line with people in front of me and then people behind me and then told me they were only taking orders from deliveries. Why in the world would you let customers get into a drive-thru they can't get out of and then refuse to take their orders. What a terrible organization. They won't miss me and I certainly won't miss them.

I ordered a some food to eat inside and they forgot the utensils when I asked for them the guy at the counter said they didn't have any and acted like it was no big deal that I had no way to eat my meal, it was a bowl so I could not eat it with my hands. He half hearted looked around, I should have asked for my money back. I will never eat at this location again.
