Lifelong McDonald's fan here sharing his thoughts on the brand new BIG ARCH BURGER, the hamburger conglomerate's first new entry into the burger arena in over a decade. On Tuesday, McDonald's CEO Chris Kempczinski elicited global ridicule for the perfunctory, guppy-sized nibble he took when sampling his chain's vaunted new product. Your favorite Yelp correspondent is here to report that you can take much more than the hesitant, half-bite the squeamish CEO took- The Golden Arch is an excellent new entrant. The sandwich plays like a hybrid of the Big Mac and the Quarter Pounder, featuring: -Two thick, QPC-sized patties...not the skinnier patties you typically see on the Big Macs or regular hamburgers; -White American cheese; -Two different types of onions, including fresh sliced onions¹ along with crispy fried onions. Note: The fresh root vegetable aren't the "world's smallest slivered onions" that so many of us Mickey D'ers love. -Framed between sesame/Poppy seed buns, lightly toasted -Chilled lettuce and pickles. I ordered mine, as always, sans the offensively foul pickles. -Trademark Big Arch sauce, described as a more tomato-forward, tangier counterpart to their traditional special sauce The burger is served in a cardboard box and is a definite "two-fister." It eats very well- You get the unctuous meaty beefy flavor from the meat, the creamy cheese, tangy but not overwhelming sauce and the wonderful mouthfeel of the crunchy onions against the thick, toasted buns. Service was decent but not exemplary. I was asked to wait in the "pull ahead" space for six minutes. I realize its a brand new concept to the restaurant but my custom order (no pickles) certainly doesn't compute w/ a six-minute extra wait! I paid $14.72, taxes included, for a Big Arch Combo (go large) with a hamburger on the side. Notwithstanding their CEO's humiliating, half-bitten "endorsement" video, the folks at McDonald's Corporate can arch their noses skyward why they look down disdainfully on their competitors, 'cause the Big Arch represents a big step in the right direction. read more

Enjoying the barely warm hash brown that they originally forgot to give me. The lady said that I insisted on not hash browns with my eggs McMuffin meal. Hmmm... not so... There's no more ordering off the screen inside. In fact, the screen is just a quick advertisement. They want you to use the kios instead. And the egg McMuffin was cold. And then there's a guy on here complaining about people with bad reviews, yet the end of his own review was complaining. Write about your own experience and leave other people out of your reviews.

I came to this McDonald's in Diamond Bar with my Mom to redeem some free foods from McDonald's rewards since the points were about to expire. Thank you McDonald's! I wanted to go through drive-thru, but internet reception was not the greatest from the outside so I had to walk-in to order. Exterior was pretty clean. Inside was just as clean. Nice holiday decorations still in place. I used the kiosk to order... it was easy peezy. Friendly and nice gentleman staff gave me two kiddie cups for water upon my request. Btw, you can't order water via kiosk. Just ask for water cups at the front counter. Thank you Sir! Got my Mom's Big Mac in a jiffy! We left and came back after 15 minutes for my Filet O Fish. Why you ask? It is because you can only redeem one food reward every 15 minutes. This time around I went through drive-thru with better WiFi signal. Staff was friendly and nice as well. Got my Filet O Fish in another jiffy! Friendly staff, great fast service, and good tasting foods. That's the way we like it. Well done McDonald's! read more

To the guy who assisted me today, I think your name was Aaron. You were very kind and had exceptional customer service :) This McDonald's was clean, quick, and had very friendly staff, that not all McDonald's do. Fries were crispy, not too oily, and very very efficient service. Thanks! read more

We got two happy meals and one filet o fish sandwich only and they gave us wrong burger. We noticed in a bit because when we were going to eat them on the way to somewhere. They need to check their orders before they give out. We got quarter pounder with cheese instead... which means we pay extra for cheaper burger. Anything they are going to do about it? I suggest to check your orders before you leave loll read more

This McDonald's has been updated and has 2 kiosks. The place is busy during meal hours. I had a tricky transaction using the deals from the app so wanted to use a cashier. After waiting for one she just tells me to use the kiosks. So I'm trying to figure out the kiosks doing their job. Ha thanks McDzz Nuts. read more

Yep, Awful as usual! The Half frozen chicken nuggets, fresh fries, and fresh mcchicken sandwich are what I received. Total wait time in the drive through.... 30 minutes 11pm to 1130pm basically. I had asked for fresh chicken nuggets and had me waiting at the 2nd window for a long time. So upsetting! read more

McDonald's - When you order a 6 piece chicken nugget order, you will receive 5. This is the second time! - Fast Food Near Me - Diamond Bar, California

I'm big when it comes to customer service. Marlins customer service was horrible. Idk if he was having a bad night but his service sucked. When i received my order didn't even offer me any condiment's i had to ask him myself. Not even a, "have a goodnight" when i drove off, nothing. Definitely didn't like his energy, he came off rude. I usually don't go back to places cause of workers like him but ima give him the benefit of the doubt to see if management corrects it. read more

We ordered food on the app and paid for it. Bit when we went into the store the guy said the charge didn't go through and made us pay AGAIN! The receipt even shows that the order was accepted on the card!! Well, we we checked our statement and the charge is still there. These people are crooks!! I'm sure the guy behind the counter pocketed those extra funds. I would also add that the total amount for the same food was different. It was more expensive on the app!! read more

Worst McDonald's visit ever. Ordered 4 items, only got 2. No sauce, poor quality, and careless service.

VERY UNDERSTAFFED!!! The back young girl working at 9:50am on 02/15/26 is very rude. I heard her rushing an older gentleman to order and stated "sir i'm very busy- can you hurry and order." I heard her say that she is super busy to customers many times- not a very welcoming environment. I felt so bad for all the older people ordering inside this establishment. There were NO utensils and straws where the soda machine was but they were very impatient when so many people came up to the desk asking what they needed. As i'm writing this, she sent the old man away twice instead of helping him. McDonalds do better, not just the staff but whoever is in charge of scheduling! Everyone here is working hard and it's management's fault. read more

i'm going to say this mcdonald's is going to be up in the top 5 slowest and managed mcdonald's of all time. ten parties waiting for food inside. about 15 cars waiting in drive through. took 25 min to get a mcflurry and nuggets. read more

First they tell me that I placed my mobile order at the wrong location. Then they tell me they gave my order to someone else but they can't remake my order. Told me to cancel my order in the app but it does not let me when it detects that I'm already at the store. If their staff messed up, why can't they simply remake my order? Contacted corporate who forwarded my issue to the store. After a week, a rep reached out. I show them my screenshot with my order info and they told me again I placed my order at a different location. My screenshot has their address. They couldn't explain why their staff couldn't simply remake my order and have stopped communication. read more

My go McDonald's. Rarely do I go in but when I place an app order, curbside pickup is smooth. The orders are normally accurate, and I'm used to getting the food fresh. Even though the app is convenient, there have been a few times where I sat outside too long to find out the app malfunctioned. Either way, the staff is polite, in contrary to the crazy bad reviews here. At least from my experience. read more

Second time they messed up my online order, came back home to find missing 1 burger, cmon man, do your job.

Arrived at 9 PM,no service and no staff in sight. Waited 30 minutes for a small order while they prioritized the drive-thru. Unfortunately, I didn't catch the employee's name--just remember he is bald (big bald head). Food quality ok, is consistent with past visits read more

McDonald's - McDouble - Fast Food Near Me - Diamond Bar, California

Worst location. Food is always cold, fries soggy, tables dirty, and the older lady staff especially does not listen. She is too hyper focused on doing what she's doing quickly that she doesn't listen. I'm talking to her asking for more napkins to clean the nasty table and she responded with "we don't have anyone to clean right now." If she had listened, she would have understood what I said. I also told her no need to bag the food, and she responded with "I'm working on it" and proceeded to bag the food. If she would have listened, she did not have to do her job twice. Now I know why our food is always missing or wrong at times we opt for drive thru read more

I ordered a chocolate sundae and this is what I got. If I was at the store I would have said something. But I ordered through uber eats. This is sad. How hard can it be to serve ice cream in a cup. Straight lazy people. read more

McDonald's - I ordered a vanilla Plain Sundae. They didn't even fill it up. No peanuts. No ice cream basically. Do better McDonalds. - Fast Food Near Me - Diamond Bar, California

Our 2 prior trips here the food was good & the fries were hot & fresh. Today, not so much. Waited 20 mins for our drive- thru order while 5 cars behind us got their order & drove off. Finally someone checked on us as we were parked at the front window waiting for our food. We could hear someone say that our order was closed out. Not good! The food was cold & cheese burger made very sloppy with the hamburgar & cheese hanging half way off the bun. We got ice cream and it was half melted while waiting. It wasn't busy & no excuse for this to happen. Too busy talking and playing around. Mgmt. needs to monitor better. read more

Went through the drive thru and there are no prices on the menu. I will not go to this location again. How do I know i am not being overcharged? read more

I've never had an issue with this location. I always order via the app for mobile order pick up and it's been ready, quick, and correct. Food is always warm for me and flavor is the same as other locations. Location can be a little tricky to get into as it favors one direction. read more

I am a student at Lorbeer Middle School down the street, and I am a regular to this McDonald's. I have never had an issue with my food at this McDonald's except for random backstages (mostly when I get curbside). What pisses me off about this McDonald's, though, is the treatment of the students. There have been some almost none student-involved incidents but they kick us out everyday. Us students can't stay in this McDonald's after we receive our food, can't even sit down without being told to leave. Most of the time, the McDonald's is near empty yet they kick us out! As a customer we have the right to stay inside. I, as a regular, do not recommend this McDonald's for any student, let alone adults as some get annoyed of the 15 kids outside waiting every single day only to get kicked out 5 minutes later. Do not recommend. read more

Bring your own rag to wipe off the dirty tables. I went with 2 friends on a Sunday night about 7pm.

Always check ur food before u leave, yall always forgetting its,I'm so mad ,food isn't cheap ,this mc doanlds is horrible

This has got to be the worst location in the world. They literally have idiots as employees. They forgot my daughter's toy and the happy meal and that's literally the whole point of the kids happy meal lol they also forgot my son's fries and his happy meal. What a waste of time. You call and talk to the manager, and he is completely clueless. read more

I went here at 2 am just for a Dr Pepper and some cookies. When I got to the window I asked if I could get the cookies made fresh if possible since there wasn't a line or anything like that. I proceeded to pay then the lady made me park for 8 minutes when they only take 2 to warm up and then proceeded to hand me just the bag of cookies piping hot without a bag for them and I ate one and realized they were just warmed up and I've worked at McDonald's before so I could kinda tell they slacked off. 2/10 only because my Dr Pepper was good read more

This is based on the drive up and drive thru experience. Logistic wise the drive up parking spots are next to the drive thru area; the signs are hard to spot so it is easy to miss. There are 4 spots for drive up which makes it pretty convenient. The staff is nice and friendly. Typically they are out with your food within 5 minutes. The drive thru is fast and efficient. As for the food it is MCD standard. Nothing that super stands out such as best nugget ever but nothing that is sub par. It's worth a stop for a quick bite and ordering through the app to pick up here is seamless. read more

I went on Thursday 12/19. I accidentally left my review for this location on the Golden Springs one. Well, here's my review... I haven't been to this location for many, many years because when it was remodeled, I thought it was not good. I have been going to this McDonalds since September 2024. Evertime they have excellent service. I still don't like their parking lot though. You can only enter from the street. Thankfully there is a shopping center behind this McDonalds. All the other McDonalds I've been to like in Rowland Heights and Chino Hills have had horrible service. They try to get you to use the kiosk and act rude. This location employees help you out with app codes and other stuff. I'd like to add that it's McDonalds food. So, the McDouble was salty, the chicken nuggets were how they always are, not the best and the McChicken still tastes the same. read more

Coke was good. Fries over cooked and stale They charge for ketchup, how ridiculous! Not coming back to this location. read more

Rarely go but when I do, they always mess up the order and/or forget items you paid for. Called once and nothing they will do unless you drive back. Good luck over here. read more

If I can give them a zero star I would. $4.50 for a large fry that is half full. Simple order they get wrong. Nothing but young kids getting overpaid for their quality of work they put out. Very poorly managed store. You drive up and the monitors are black so you can't see to order. This is a great example of big corporate not caring, just taking your hard earned money. Horrible, Horrible read more

i asked for a bigmac meal w no cheese or pickles and a 4pc nugget. you mfs forgot my nuggets and just gave me a plain burger.

I absolutely HATE this Mc Donald's. 0 STARS!!! Sucks I even have to give this dumb place a star at all! Every time we try to get Uber eats and try to use the one in Pomona, it ALWAYS switches the store location to this terrible location! THE NUMEROUS TIMES that we have gotten the food from here, THERE IS ALWAYS SOMETHING MISSING. ESPECIALLY from the Uber eats, yall clearly don't pay attention, always forgetting sauces and have even forgotten a whole meal several times! This is a terrible location, TERRIBLE! Do BETTER! Yall need a better baggers or something! Hire people who know what they're doing or train them better! You do not pay attention!!!!! Every time we have figured out Uber eats changes the location, and it's this location, We always know there will be something wrong with our order. I used to work in fast food, I excused it the first 2 times, but EVERY SINGLE TIME!? BE SO FOR REAL! Clearly terrible bagging integrity, terrible managers/leads, and terrible staff in general. I will be trying to get a hold of Uber eats, or some how block this location from my account because I am so tired of Uber switching my order from the Mc D in Pomona to this dumb location. If you're reading this review and live in the Diamond Bar area, go to the Mc Donald's off Murchison Avenue. They never get our order wrong. read more

Google maps and yelp show open 24 hours a day, but clearly they don't follow their schedule. I'm here at the drive through at 1am on Tuesday morning and no cars, no food, no service.
