I've lived in the area for over 20 years and this is the first time I've ever been to this location. Obviously I don't normally go to Del Taco, but I got a coupon flyer in the mail. The coupons looked good and they were also advertising their dragon berry drinks, which I wanted to try. I was a little concerned about going - it's not located in a busy area and also all the negative reviews here. Figured I'd give it a try. Now this is based on my one and only visit. For myself, I didn't have any issues. Walked in and was served immediately. The server was very friendly and pleasant. The store itself was clean and organized. Only issue was that they ran out of the popping blueberry that normally goes in their dragon berry shake. However the server offered to put in more dragon berry to make up for the lack of the blueberry. Don't know how it should normally taste, but the extra dragon berry made for a delicious shake. I also used a coupon to get two epic burritos - the grilled chicken & guacamole and the carne asada steak. Both burritos tasty good and were stuffed. I was surprised how big they were. So my experience here was a good one and I plan to go back. Fingers crossed for another good experience. read more

The service was great and the place was clean. However the food was subpar. I really should give it a one star rating. The fries were warm at best, so I asked for fresh ones which they happily gave me hot, fresh fries. My tacos were literally half full with barely any lettuce. The shells were slightly stale. I don't know why with such low ratings nothing changes with this establishment. Del Taco use to be so good and now it's so bad. read more

What a joke! This is the second time I attempted to buy breakfast between 4-4:30 am. The store was open, lights on, but nobody responded to the drive through speaker, after waiting ove 3 minutes. I'm guessing they were sleeping on the job. I think I'm done with this location. read more

Added 2 $5.00 Clasico boxes to my order and I was told they did not have them anymore, so I asked what was in the $7.00 boxes and I was told a bean burrito for both the 7 and 9 boxes. I have gotten them before, and we get beef and bean burritos, so I tried to clarify, and the lady said no it's a bean burrito. Not what it's advertised! The 5 box is on their add for November... read more

There were three occasions I ordered a bean and cheese, red burrito each time there was no red sauce. On the second and third occasion, we clearly stated to make sure they put red sauce each time there was no red sauce. Also, the shake machine has been broken for a month and each time we asked when it was going to be repaired. They had no answer. read more

It's super unfortunate that this is the closest Del Taco to my house because it's HORRIBLE every single time. Order never correct. Skimpy made food. Rude service. It's been like this for years so here I am writing a review hoping something will change! read more

First off the manager who was working drive through and taking orders was extremely rude and refused to speak English. Little did he know I understand some Spanish and heard him and the other girl worker talking badly about others. These two shouldn't be working in customer service. The other lady basically threw my food on the tray and walked away as I tried talking to her. Extremely rude. I wont be back. read more

Had to send a positive review for this location. Been coming here forever, and although there have been times in the past where the food and service were below standard, this has improved. Staff was pleasant and there were no issues with the food. The location is not the newest, but the staff keeps the inside clean. I recommend using their app for discounts and freebies. read more

I know it's kind of silly to be reviewing a fast food place, but seriously this particular location is so great. Del Taco is a favorite of mine and I used to get it after school for years, but not all Del Taco locations are built the same. This location has consistently made all my orders correctly and made them well. The rice is never overcooked and the fillings are always placed nicely instead of just slapped into burritos and tacos. The biggest reason I wanted to write this review is the consistency in their staff. No matter what day or what time of day, all the workers are SO NICE. Very polite, repeat your orders back to you and have a great attitude up at the window. We try to take the surveys every time we order because it has always been such a pleasant experience for a fast food drive through. read more

Poor food prep conditions, service to order was slow, nobody available to take order, waited a while for someone to come from the back. Overall experience was pretty bad standards, could look past poor service but not unhealthy food handling practices. read more

Del Taco - Poor food prep conditions, No Gloves! - Fast Food Near Me - Diamond Bar, California

Ordered some carne asada fries, instead they gave me some sort of queso fries. Whatever it was, it wasn't on the menu and it was sloppy. I went back to show them the mishap, the girl straight up lies and tells me that what I had was carne asada fries even though there was no sour cream NOR guac. "No no it doesn't come w guac" then why does it have guac on the menu picture ･_･ She also tried to tell me the queso was sour cream like girl bffr. I understand mistakes happen, but don't lie in my face and treat me like I'm stupid. Just correct it read more

This is a somewhat regular lunch stop near my office. The restaurant is usually pretty clean, but not always. The staff seems to rotate quite a bit, so we don't often see the same faces working here. They're usually friendly, but we witnessed an employee/manager performing and interview in the dining area yesterday and thought some of her comments that we overheard were a little "off". Anyway, the food is always served hot and tasty. Because of the variety of menu items, it satisfies anyone in our office. I noticed a new sign yesterday that seems to promote a "fresh" theme (see pic). I'm sure this will continue to be one of our go-to spots. read more

Del Taco - New "freshness" theme. - Fast Food Near Me - Diamond Bar, California

I have gone to this Del taco several times in the last few weeks and have paid for extra cheese only to get home and have NO cheese. You need to train your employees to make sure if someone is paying for something extra that the cheese that would come on a burrito is on there and if I am paying .70 cents for extra cheese it should be more then a pinch of cheese. I normally go through the drive through and if I come there again I will sit at the drive thru and check my food at the window. Diamond Bar and Chino are the Del Tacos I frequent and I am never satisfied because I pay for extra and don't get what I am paying for. I know most Del Tacos are franchise's but Every Del Taco needs to take lessons from the original ones up the hill. Shame of the franchise owners for bringing down the quality of Del Taco. I should NOT have to drive up the hill to Barstow or Victorville to get quality Del Taco and know my food will have the extra I have paid for. read more

This place is trash. If you have to go here, order inside so you know what you're getting. They have stiffed me in the drive thru multiple times. This place sucks read more

Okay this is purely about food and food prep: Yes. It's fast food. Yes I can expect fast food. Believe it or not the drive through window associates are nice and usually on it. Del taco is my guilty pleasure until today! I asked during my order twice and was very specific no tomatoes no pico. Reassured me and read back my order no tomatoes. I asked to triple check at the window as I was paying. Yes again. I asked as the bag was handed to me--YUP no tomatoes. Side note- I only don't eat tomatoes of all the things. I get home. Well. Guess why I'm writing this? I have a little one so getting out is rough. If you have a new crawler you get it. You have a short window to eat or you wait til bedtime and who wants to cook(Del Taco it is!). I'm so sad. They were kind over the phone and asked me to come back but now it's bedtime and I'll have to come by another day.... For a refund.....on a burrito............‍ Hold on--- to top it off there was a piece of HAIR stuck in my ice in the water. Umm. It was not hair from the top of someone's head FYI. Send help. I'll be going to (dare I say) Taco Bell now‍ read more

I come here quite often. I really have no complaints. At least with the day shift during the week. The employees are always courteous and I get my food pretty fast. Sure there's been a few times where they didn't see my order. But then again I do order on the app and drive over there right after which literally takes me like 2 minutes. Other than that good customer service and they never got an order wrong. Yeah sure there's homeless hanging out there. But what are they supposed to do about it? They're just there to serve tacos. They don't get paid to get rid of the homeless. I don't even think the police have the authority to do that. So people need to get over it and quit their whining or go somewhere else. If you want to complain go complain to the city. But anyways...it's past due for me to write a good review about them. read more

This location is the worst of all. How many times you come here say what you ordered and you leave with something missing cuz they never get it right. I heard my husband place the order and I heard the woman repeat the order and yet she's still didn't put an item in the bag. This place is the worst there were two people behind us and they gave up cuz it took so long. These people do not care about their job whatsoever. They probably don't make any money so they don't care about their job whatsoever. They could care less they probably make jokes of shorting people and pissing them off. I think it's a sport for them. Let's who we who can we get this time. The worst place on the Earth. And I don't usually complain. I have nothing good to say about this place. read more

Wow, Can't the person upfront not say "good morning," or "welcome to Del Taco?" So sad. It's 9:13 on a Saturday morning 10/6. Then 3 people working on taco bar with no clue. Can you spot the chorizo? I cannot. What a disgrace!!! It just seems like they don't care. read more

I eat at Del taco often all over Southern California as I travel for work. This location is by far the worst of all. This place is filthy dirty the employees are the rudest I've ever come across especially the big girl with all the piercings in her face. I would recommend to stay away from this location based on how dirty the kitchen is. if by chance the management of this location reads this review I have a tip for you clean your nasty filthy especially the kitchen. Every time I go in there it is disgusting. read more

Terrible, food terrible service 0 rating really but had to rate 1 star to get this posted on Yelp. Also noticed they won't give you a coin to use their restroom even if your purchasing food and your a paying customer. It strictly said must be a customer to use the restroom. I saw two people leave and the Del Taco definitely lost cash flow on orders due to not allowing them a coin to use the restroom so they went to Kentucky fried Chicken and order from their instead. Heard them ordering as well. Del Taco be kinder to those exciting the Freeways passing by eating and using a restroom on their travels. read more

Came in today for lunch. There was only one other person in the restaurant. Waited at the register for about 15 minutes and no one bothered to help me. I finally left after waiting too long. Totally unacceptable, don't bother coming here is you are looking for fast service. read more

I've been to this location multiple times and used Apple Pay, but whoever was working the window today told me no and had no reason other than they don't have it. Extremely rude and unprofessional! And sorry but in a world with a virus going around I prefer a touch less way to pay to help stop the spread. read more

Everyone be careful!!!! Watch the workers making the food in the back to see if theyre wearing gloves. The guy working the evening shift at the Diamond Bar location does NOT NOT NOT NOT NOT wear gloves when he's handling/ picking up the cheese, lettace , tomatoes etc. What a health hazard. These are all either moist or wet foods, not dry. Even All the taco vendors out in the streets wear gloves. WATCH OUT!!!!!! It's just a matter of time before someone ends up getting very sick from that man handling moist/wet foods with his bare hands. Just a matter of time. read more

I used to be a regular here but not anymore. I order a deluxe Del beef burrito with extra cheese and sour cream and get what you see in the picture. No lettuce or tomato and where is the sour cream? Extra cheese I think not. I always order inside because you know what happens in the drive thru. Being a regular I used to inform management and then she says I'm picky. I'm picky because I want what I order and what I pay for. The 2 extras are $1 more and when they do give you extra its a 3 cent pinch. I've seen them do it for to long. IM DONE. Ill see if I can post the picture. Don't see the option. I would avoid this place at all costs. The people who work there are nice but I want my order correct. read more

Unfortunately 5 days ago I caught e.coli food poisoning from this location. I ordered 3 del taco and the 3 layer nachos around 11am. It was my first and last meal that day. I'm currently still dealing with the leftover symptoms watery yellow stool an a outrageous amount of gas 5 days later. I pray that whomever the person or people that prepare the food, takes the job more seriously. I would hate for someone's child to deal with this type of food poisoning or even die from it. If you hate working at Del taco that's understandable. However professionalism and enthusiasm can take you many places alone. read more

My boyfriend did a DoorDash order from your guy's establishment and got me tacos earlier i mean which was nice on his end, but the establishment must want me to end up in the hospital and die--- i am HIGHLY allergic to onions, you stupid people don't know how to read. Your about to lose a loyal customer-- like seriously!!!! I want a management person to respond back to this cause this could of been my life. Either offer some kind of free meal to me or I'm done eating at your facility--- NOT KIDDING!!! read more

I am giving this location three stars based off of my first and only visit, so this review may not be accurate. I went through the drive through and placed my order (a $5.00 fresh faves box, cheddar potatoes, and two beyond meat tacos). To be fair, the location was busy when I went (about 17:30-17:45), but even though it was busy, they shouldn't sacrifice quality to get their lines down. My fresh faves box only came with half of what it was supposed to, they only gave me one beyond meat taco, and no cheddar potatoes. I also asked for a variety of sauce, but they only gave me all mild. The employees were nice. They were very nice, but they made me feel so rushed. They walked away right when they handed me the food and I waited about three extra minutes at the window (I used to work dt and I know how every second counts, so I didn't want to wait longer and screw up their times) and they just never came back, so I parked and ran in with the food and my receipt. Now, like I said, employees were nice, but they shouldn't sacrifice quality and customer happiness just to rush us out of a line. Either way, I've only been to this location once so hopefully this doesn't reflect how they normally run their business. I'd try it out once or twice more just to see, and when I do I'll update the review. read more

I unashamedly love del taco and have been eating it since I was a kid. But this is by far the worse del taco I've ever been to. Ordered a bunch of crunchy tacos for the family only to get home to discover that ~70% had the amount of beef you'd expect while the rest had ZERO beef. On another occasion I ordered the mango habanero crunchy chicken taco only to get home to discover the lady had given me a plain crunchy chicken taco someone had clearly changed their mind on. No sauce and ice cold while the rest of the food in the order was still warm. read more

This location again likes to take your money and not give you all of the items in your combo. I'm missing my cheese quesadilla from my #6 combo. If you go here you might as well hold up the line longer to check your bags to make sure you get everything you paid for. I know how hard it is working fast food and things may go unnoticed, but a regular cheese quesadilla? read more

I've been going to this Del Taco for so many years. I have always had the most pleasant experience here. Once in a while if something is missing or not quite right with the order, they take care of it right away with no hassle. The vast majority of times I've been here our order is 100% correct. The employees are so competent and friendly. This is one of the best fast food locations in the area thanks to the wonderful employees. read more

This Del Taco is hit or miss. The food turns out good at times, but is rather dismal on other occasions. I've only gone through the drive thru; I've never eaten inside the restaurant, so I can't comment on that aspect. The workers have always been nice and have always gotten my order correct, so no complaints there! I always get tacos, burritos, fries, or quesadillas from Del Taco. At this one, I've received cold food or dried out and old tasting food at times. However, on good days, the food has been hot and tasty. I actually prefer to go to the other Del Taco in Diamond Bar on Golden Springs....I've had much better experiences there. There's a $1 charge to use ATM/debit cards and they don't take credit cards! read more

The last couple times I got hash browns, the hash browns have a fishy stale taste. I think the oil they use is old or not clean. Today I got a chicken taco and roller. Had moldy cheese in it, grossed me out. I've had chicken for my soft taco before also very watery and oily. The quality at this location is always inconsistent. read more
