Wrong order and I repeated it twice and still got it wrong. I paid $15 for the combo that your employee chose for me.
Update: No worries , I still ate it..i was just hangry and they got my order wrong so I left a review , but I’ll be honest the burrito wasn’t my choice but the fries were delicious!

This Is my first time eating Del Taco. And I don’t know why it has been my first time. However, I ordered a burger and some fries. And the burger was a little dry, but those fries are outstanding… 4 days later on our way back home. We stopped again and I ordered a burrito I think it was some kind of a combo burrito and let me tell you that was so filling.. it was tasty and I could only eat half of it, I also used the inferno hot sauce cause I was thinking it was gonna be more like Taco Bell hotsauce, but nooooo this sauce was pretty much on fire. It was. It was really hot coming from somebody who eats a lot of chili. I was pleasantly surprised and I will be going back.

The food tastes bland and it cold and the service is terrible and the atmosphere is terrible and the overall experience is terrible and I will not come back for more.

The lobby and seating area are very clean. The food is good. The best part is the employees, very friendly! And when a man in a wheelchair came just minutes after they closed the manager opened the locked doors to allow him in to eat.
I use the drive through to get breakfast after I pick my wife up from work. She’s a nurse and works nights, this is our favorite spot to get breakfast on our way home. They always get my order right compared to McDonald’s in Diamond Bar that can’t get an order for four things correct. I see the same manager almost every time on the weekends and she is so nice! I don’t have to ask her for my senior discount, that makes the price even better!

First time in a few years to any DelTaco as they are not nearby. Frankly I was disappointed. The regular taco was okay, the meat was not a good high temp at all. The fish taco was very disappointing. I remember them being pretty good this was a turn off. The Dr.Pepper seemed to be broken as there was no syrup and it was overall broken or they didn’t want to change it. Not the relaxing experience after 3 hours on the road with 5 more on front of me.

Lights are on, but nobody is home… Are you guys open 24 hours, or did your staff fall asleep?

Becareful when you go there they gave my order to someone else in an audi and then they gave me the unwrapped burrito in my bag. Not cool once i got to my destination and seen how it was i checked my dash cam and sure enough. Now i call to get a refund and it goes to voice mail never again

This one is hit and miss. Usually the food is hot and fresh but other times they forget the extra cheese or the churros are hard/old. The carne asada fries got smaller too because I get them as an add on to the combo (cheaper ) and they went from giving maybe 2 handfuls of crinkle fries to half a scoop and the rest was toppings and some meat lol. The carne asada is alright not the greatest. My favorite is the chicken burrito minus lettuce. Last time I ordered it it looked all mushed up inside and I didn’t see much cheese or sauce but I guess it was an off night. I recommend ordering from here during the day cuz their night crew is lazy/sloppy.

THE CITY OF DIAMOND BAR needs to shut this dump down asap. I’ve lived down the street for 5 years and this del taco has always been terrible. Food is always cold….the employees look extremely suspicious and close the store when they feel like it. I think the only requirement to work here is to have a heartbeat. Place is a health hazard. Don’t come here
