The lady working at the drive through on 8/25/23 at 9:54 has the absolute worst attitude. She needs some customer service training because absolutely not. She has red hair, it’s no one’s problem but hers that she works at del taco don’t be so aggressive while someone states their order.

I just went through drive thru and they gave me the smallest bold burrito looks like only tortilla and the wrong hot hot sauce when I asked for inferno

Bad experience with this location. It smelt very bad, like if someone pooped and they just wiped it off. The cashier was a bit rude, and didn’t tell us that it would cost more for a upgraded drink. I wouldn’t recommend visiting this location, and I don’t believe I will be going back. The smell alone, makes me believe it isn’t a clean and proper environment.

I think the employees mean well but they are always out of stuff or getting orders wrong here. Also doors still closed at 8am to dining area which is ridiculous.

I generally love Del taco, I think their food is great, but not at this Del taco. It is bad enough when you pay $.60 to put sour cream on a $.79 taco but when they put just enough in the taco that you can see it but not taste it, it shows they just don’t care. This place sucks.

Del taco is great affordable food. I wish they used homemade tortillas. Great place when the tortillas and shells are fresh.

They let me use the restroom. I was on my way home from work, and I knew I wasn’t going to make it. Man, I blew that bathroom up!
