1) Open 24-hours inside and drive thru. 2) Busy after 11pm because of all the college students that meetup here. 3) This location sits in a Nice newer developed area, safe, and relatively clean: ) read more

I come here for frappes before work. Fast service. Cashiers are friendly/helpful. Restrooms are clean read more

One of the worst McDonald's on the planet. They do not sell long lived products such as the Big Breakfast and put so much salt on their fries you might as well eat a salt lick. The staff routinely looks confused and the store management is useless. read more

After eating here a handful of times to fulfill my Mcdonalds craving, let me tell you that my McDonalds craving definitely was not satisfied. Today is the last day I will be ordering from this location. I have never came across terrible customer service only TERRIBLE FOOD. I ordered Fries and Chicken McNuggets and BOTH the fries and McNuggets are STALE, COLD and INEDIBLE. I literally tried to feed the McNuggets to a random dog that was roaming around my neighborhood and the dog didn't even want to eat it. The dog sniffed it, hesitated to eat it and instantly spit it out. I'm at the end of my rope with this location. Never. Again. read more

They offer punch cards for their mc cafe drinks! They don't keep it a secret like other locations do! I've gone to different locations since and asked if they have the same card (card is only good for one location) and they've all told me no! So they either don't know or management doesn't want to participate in this awesome program! Considering I drink coffee every morning this is a big perk for me! Their food is never dry like some McDonald's can me. This might seem lame but something that I use to see at all McDonald's was a trash can at the end of the drive thru. They've seen to have taken that out at a lot of locations, but not this one! Old faithful is there to help me get ride of the cups I forgot to take out and make room for my new drink!! read more

McDonald's - I drive out of my way most days to go to this McDonald's! They offer punch cards for their mc cafe drinks! - Burgers Near Me - Walnut, California

Slowest drive thru ever ! The cars don't move at all. If u are in rush avoid coming to this macdonalds

For several times they served me cold pre-cooked food. This noon, they didn't even mix the glazed tenders well enough. It was like they had the chicken in the box and poured the sauce on them. I know it is crowded, but you have to find a way to always serve food at its best taste. That's how businessmen respect customers. read more

If you like your fries greasy and tasting like a fillet a fish then this is your place. If you like slow service this is your place If you don't need napkins , or condiments this is your place. If you have all the time in the world to get through a drive thru than again this is your place. Sorry , I got a life I need service. read more

Every single time I go here they always forget something and when I call to tell them they make it so hard

Customer service has definitely taken a huge nose dive since 2010. From 2017-current... the new hires are unbelievably RUDE!!! When you pull up to the drive thru you never get a thank you. Just a "What do you want"? And the tone is always as if I'm bothering them. It's sad because all the great employees and managers seemed to have been replaced. Management needs to be more selective when it comes to hiring team members. This place is a disaster. Never coming here again. read more

What I'm about to mention here is a huge gripe I have about this place and is a big reason why I am only giving it a two star. I really hope somebody from corporate reads this and will implement some changes. The two lane drive-thru that converges into one lane is a HORRIBLE.... HORRIBLE..... RIDICULOUS idea. And I'll tell you why.... This morning I left for work 30 minutes early, in a happy jolly good mood and decided to stop by Mc Donald's for a coffee and breakfast burrito. When I pulled in the drive thru was packed but I figured since I have so much time to spare it was alright. So I went into the left drive-thru lane behind an SUV. The other lane had a line all the way around the curb. By the time the SUV was able to move forward to order, the other lane already had 2 cars go through with their orders. When the SUV in front of me finally pulled up, the lady had her little 5 yr old daughter in the back place the order. And I saw she was just staring at the menu and couldn't quite make out whether she was having issues with ordering the food or what, but this whole time I was watching the other lane going through car after car after car. By now 5-6 cars that came way after me had already placed their orders while I'm still stuck behind this SUV where the woman decided it was a great day and time for her daughter to learn how to order through the drive-thru on her own. Since all the cars saw what was happening behind me they started flooding into the other lane so luckily for me I was able to back up and LEAVE. Unfortunately for me though, I spent 15 minutes trying to get breakfast and ended up leaving empty handed. I could have just parked and walked in, but when I did that in the past I ended up waiting even longer inside because typically fast food places have this mentality that dine-in customers aren't in as big of a rush as drive-thru customers. So they tend to expedite the drive-thru orders a little more quickly. When this Mc Donald's first opened and I saw the dual drive-thru I thought it was the most RETARDED idea ever. I'm surprised there hadn't been more customers complaining about it. read more

Excellent service by Rocio, one of the Managers, very helpful , asset to company. The place clean.

Never going to this location again. I went in for a large 10pcs nugget meal, large sweet tea and hot mustard sauce but got medium instead and they didn't even give me the right sauce. This is the second time I have experienced this at the same location. read more

Customer service and urgency is obviously two words that this staff does not have in their vocabulary. After repeating my order what seemed to be a thousand times, they still managed to mess it up. Then they try charging me for an item that they messed up. I explicitly asked for an apple pie and they gave me apple slices. When I told them their mistake they try charging me the 0.58 cents left over. What a waste of time! I am not a freeloader but they should correct their mistake!! read more

McDonald's is absolutely disgraceful. The food is gross and It probably has much protein as a cockroach. the service is horrible because they forgot about like 16 times and they don't even feel sorry about it, do not go to McDonald's it's unhealthy and not even worth the wait. read more

You guys this had to be the funniest trip to McDonalds we have ever had. First off, I have to say that this location is really nice and modern. It looks new or at least newly updated. They even have a cool new kiosk to order from. I was super nerding out to use it until someone at the counter called me over. Ugh, next time.... Anyhow, service was nice and pretty fast. All was going pretty typical. We got the drink and grabbed a table. They even gave us a number to post at our table so they can bring our food. Yeah! So we ordered the two cheeseburger meal plain and a six piece chicken nugget on the side. Simple enough right??? No, not at all!! First we opened the nuggets, the 6 piece was only 5. Hmm, okay easy fix, I went up and they gave me a new one. They could have just popped a little guy right in there but anyhow I was on my way back to the table. Next up, first plain cheeseburger. Well, it was just bun and meat, no cheese. Hmm, okay weird but okay. I'm on my way back up to get the cheese. Another cheeseburger was made and I was on my way. Next burger up!! My son opens it and there is just bun and cheese, no meat!! What the heck?!? I couldn't even be annoyed, we were laughing at this point. First we were missing a nugget, then the cheese and now the patty. They were nice and fixed it every time but that was pretty crazy. I should have used the kiosk! read more

kitchen department manager, really bad attitude, blaming customer for not paying even though it's paid. realized it was a mistake and not apologizing made customer really uncomfortable. Overall a really bad experience here. read more

It's mcdonalds here. The kids here smile. They have fat viet kid who says welcome to Mcdonald (viet accent), which is hella funny. It's fast food. It's always semi full in here. Lots of college students just studying here. read more

Yea idk what has happened to this McDonalds location, but man it has slipped badly in multiple aspects. Like service, wait time, and food quality. The last few times at the drive through have been awful. Last time I waited almost 20 mins for food with only 2 cars ahead and when I did get my food it was completely disappointing. The spicy chicken sandwich and fries were cold and soggy. The chicken almost tasted dare I say "frozen"? read more

Went through the drive through hoping to get my food fast and go. I've been waiting patiently now 15 min!!! Two people came by to ask what I've ordered and still nothing? This is ridiculous! read more

Where do I start...... I've given this place so many attempts and they never seem to change it around. I decided to stop in to get lunch through the drive through and my fries were cold and soggy and just gross. I ended up going in the store to ask if I could get some fresh fries she gives me attitude and comes back in seconds and says here these are hot. I leave and get back to the office the fries were even worse than the first round and the nuggets were so disgusting I ended up throwing it all away and starved after spending $7 on this garbage. I requested a call from management but have yet to receive one...steer clear of this place or just expect cold, soggy, stale food. read more

Had me go to the kiosk and order from there and I had to send my food back I'd give them 0 stars but the app doesn't allow that so 1 *

Really? Why...I only got 8 nuggets out of 10? I swear the order is for 10!! The meal is incomplete. First sign. Next, whoever the person pack the food need to get some training. My french fries were outside the box and the grease gets all over the paper bag, then onto my leather seats. ok MD, need to train your workers to do both packaging and food inspection. What a day when you're hungry at this time. This is what happened when I decided to go to fast food last minute. Lesson learn? It should went over to CF. read more

By far one the dumbest McDonalds out here. Only come here because it's 3 mins away from my house. Almost every time my order is messed up. I always have to come in from the drive through to correct it. Dine in is the same as well. Nothing but dumb high school kids working there and drop outs as managers. read more

How are you going to take my order for nuggets, ask me what sauce I would like, then give me no sauce in my bag whatsoever? Very confusing, but this location has lost my business. Plenty of other McDonald's locations who get my order right which I choose to dine at McDonald's. read more

Worst fucking service ever!! DO NOT GO HERE! Just went here and gave them a 5$ gift card with a 5$ bill. I wanted her too use the 5$ bill, and then the gift card would be used for what i owe. I only spent 5.49$ . She didnt get it at all. She thought i wanted too reload it. I barely go here.... I don't even think they deserve one star Was so mad that i just drove off. read more

This particular location consistently gets the order wrong and they have little or no quality control. The managers need to be retrained or replaced. I wish I could give it no stars. read more

This has to be the worst mc Donald's I have ever been to in the whole world !!!!! I ordered a quarter pounder combo meal and egg mc muffin to go, it took 20 min to come out and when I got my order and took off the forgot a portion of my meal, the burger was soggy and mushy, can't describe how nasty and disgusting it looked like the fries were soooooooo old and everything seemed as if it were sitting for an hour!!! I through my whole entire meal in the trash as I got it !! Do not come to this place ever for your own safety ! In top of all that they had my credit card inside the whole time I was waiting and I asked for it and they gave me attitude ! Hope this place shuts down read more

To whomever fried the mcnugget at 7:20pm on dec13th. That mcnuggets was the best i ever had in my life. It is lightly crusted, juicy and soft in the inside. The batter is so light I start doubting did your corporate updated the receipe on the batter but i think that was some how the timing you guys put in. Regardless, that is the best mcnugget experience i ever had. read more

Friendly female cashier was very willing to help. She was able to get my order correctly and had a great smile. Great experience!

I was waiting on my order and it looks like my order was a bit backed up so the manager saw me waiting patiently and gave me a large soda and small fries. Thanks so much for your hard work! read more

It sucks because this is so close to my school so I wish it could be better! It's cheap of course so that's a plus when you are looking for a quick bite to eat. However, the fries are never golden and crisp. They give me brown limp fries every single time! And the chicken nuggets are so disgusting. they taste old. I've been here about 5 times and I've experienced the same disappointment every time :l read more

The manager or supervisor, the gentleman who was wearing a tie, looked over at the line and just rolled his eyes and walked away. I waited for a few more minutes and just saw him on his phone and not trying to take any orders. Also, while waiting I was able to see one of the workers take a sip of the drink before putting the lid on and then giving it to the next customer in the drive thru... read more

Compared to a lot of McDonald's in the area, this has got to be the best, within 10 miles for convenience, food, service, accurate, cleanliness. It is amazing how bad other McD's are in the Diamond Bar/Walnut area. This one shines with a clean, updated interior, double line drive-thru, quick in-store service, lightning drive-thru service, very decent food quality, and french-fries that are soooo good, they set the standard for fries out of all the McD's in the area. read more

The worst customer service. They messed up my order and told me to wait and they would bring out rest of my order. They didnt. Had to go inside and they still didnt make it right. Complained to manager josh and he seemed not to really care. Dont go there read more

This McDonalds is consistantly slow. So often at the drive-through, i have been directed ro park amd wait for my food. Not good.

Dont go here. I ordered a large and they gave me a small for the large's price and didnt exchange it for me. Fries are sooooo old and nasty. They keep "changing their breakfast time" as if it goes according to the worker's laziness. I would go in at 10:30 to order a burger, they tell me its still breakfast. So the next time i go in at 11am, and they still said it was break fast till 12. Are you guys just fucking lazy? read more

It's 2 am on 12/11/14 and they're closed, even though they're supposed to be open 24 hours. So glad I drove all the way over here.

What the heck McDonald's? I ordered a sweet chili wrap and it wasn't even wrapped. Did you guys just dump the chicken and veggies into the box? What gives? Also, customer service is terrible. Some Asian girl seemed to hate her job. No smile or please and thank yous whatsoever. If you hate your job then just quit. We're already in a rush for lunch, don't need your attitude as dessert. read more

McDonald's - Sweet chili "wrap" - Burgers Near Me - Walnut, California

Only 2 meals per car allowed in the drive thru? Where did this come from? Horrible idea and horrible customer service. NOT Lovin It.
