This McDonald's is super convenient since it's right near the busy intersection of Grand and Valley Street. It's located in a bustling shopping center, so you can easily get in and out, especially if you're using the drive-thru. Despite the crowds, it's pretty straightforward to access, which I appreciate. I usually go through the drive-thru, and it's always different staff each time, but the service is consistently fast. If I compare it to other McDonald's, I'd say it's pretty average. It's not the best, but definitely not the worst. The staff do a decent job. they take your order quickly, and if there's a big line, they might ask you to pull forward and wait for your food. I ordered a crispy chicken sandwich, and it was just okay/fair, really. The food was on par with what you'd expect from any McDonald's, so no real surprises. Overall, it's a solid, convenient option if you're in the area. read more

Worse McDonald's in the area. Terrible customer service workers don't say anything but hand you the food, also they need to hear your order like 5 times over the speaker & when you get to the pick up window they still get the order wrong lol took forever to get our order as well. Very incompetent lazy workers. No one cares at this place. Save yourself the trouble & go to another McDonalds!! read more

Ordered through the app then waited in the store for more than 25mins and still didn't receive my order. I left without food because my lunch break was about to be over. read more

Reluctantly, one of my work week lunch stops. This location consistently has bad service (staff not well-trained and always seems to turn over). The front lobby layout is horrible, as they've installed multiple order kiosks which crowd the already tight space and have only one person at a register. Usually, that person has so much difficulty taking and getting the orders correct. Perhaps they stick all their new employees there, but with little to no oversight. I usually go through the drive thru which is much better than inside. The inside has its own issues, a soda machine that often needs cleaning/re-stocking of lids, straws are kept at the front counter, away from the soda machine, and napkins and condiments must be requested from the already busy staff. They still provide to your-table delivery when your order is ready, however yesterday I didn't receive a number placard, so the young man walked right by us twice, before calling out my order number. I ordered a burger with "no onions" and of course got onions. The parking lot is shared with a Panda Express, Applebee's and Panera Bread, so it can be tough to find a spot at times. I recommend the drive thru. read more

When you order a Monopoly meal you expect to get one. Guess this McDonald's can only get an order half right, as I got 1 of 2. Overall you have to watch this place like a hawk the order is only right half the time. read more

McDonald's food is pretty standard and exactly what you expect -- nothing surprising, but reliable when you're craving something quick. The only thing that has really changed is the price. Everything has gone up so much... paying over $3 for a cheeseburger makes me feel like I'd rather just go to In-N-Out instead. The fries are hit or miss here. Sometimes they're fresh, hot, and crispy (perfect!), but other times they come out super brown and not very appealing. It really depends on timing. The ordering system is also a little tough. With the kiosk setup, it's hard to get a staff member's attention if you need help or want to ask something. The whole process feels less approachable compared to when you could just talk to someone at the counter. Overall, it's McDonald's -- convenient and predictable, but the rising prices and inconsistent fry quality make it less appealing than it used to be. read more

So disappointed, this location says it's open 24 hours and as I stopped by at 4am and the drive thru is closed. They should be updating their opening time it's not accurate. read more

I always use the MCD app to order at this location because they have 2 drive-throughs and they move quickly. They also miss giving some items when they are busy. (so make sure you double-check your order before driving away) Their fries are made fresh and crispy. I had to go to the restroom before getting my order but the restroom door was locked and a worker there helped me to punch the code right away. read more

This McDonald's location is located next to Mt Sac and Cal Poly Pomona so it is always extremely busy. Unfortunately due to it always being busy, they often mess up orders. I ordered a 6 pc chicken nugget happy meal and a filet o fish without tartar sauce. They forgot my fries in my happy meal, didn't give me any of the sauces I ordered, and didn't give me any napkins. I found myself having to go up to the counter several times to ask for things and it took a while to get a worker's attention due to how busy it is. I would prefer to go to a different McDonald's over this one if I have the time to drive to a different area. read more

Incomplete order via drive thru and the drive thru line is always really slow. For a fast food chain, this is terrible on a Saturday morning. I had the drive back to this location to get my missing breakfast sandwich. They have one job and they messed up. This happened twice to me now. read more

the staff is super kind at this location! they deserve a raise for sure! very appreciative of the level of professionalism

This McDonald location is actually really nice. I've lived in the area for the 10yrs and I've never had issues when I go here. Compared to other McDonald location, the service is great and people are always nice. That's just my take and experience. McDonald's fries are the best-yes, I said it! read more

Had me pull over from drive thru at around 5:00PM, had to wait an extra 10 minutes. Just for them too mess up my order and guess what I order. 2 snack wraps and medium fries. AND THEY STILL MESSED UP!!! read more

One star for good WiFi access One star for quickly getting order ready Came here for breakfast and to study for a couple of hours. Ordered from kiosk. Sat down and there were many tables available but no plugs so make sure you have fully charged laptops or have portable chargers. Table I wanted to sit at was just cleared by 2 customers and a worker was kind enough to clean up before I sat down. Connecting to WiFi was easy. This was important because I left my hotspot at home. I needed a good 2 hrs to get work done. When food came, I asked about coffee refill. It was rudely answered with "yes but only one refill". Could not help but be taken aback by the tone. It's McDonald's coffee for heavens sake, count yourself lucky someone is willing to drink it, but whatever. My other reason for pulling a star was ordering through the app for table side service. I entered my table number and continued my studying. Then apparently my order came up and worker kept yelling it. Maybe it was me but I got a little more than annoyed, was this their version of table service? Walk yourself up to the pick up counter and get your own food. Anyhow I finished my homework and was glad so that I was out of there. This was my FIRST and ONLY and LAST time going here. If you need more details, I'll be next door at Panera. Their WiFi is strong, better customer service, actual plugin for your technology and free (coffee/drink) refills without attitude. Thanks McDonald's for making this decision very clear! read more

This is the first time I've been to a mcdonalds, I asked for extra pickles, and they actually gave me SUPER EXTRA PICKLES. Usually they add like 2 or 3 more. NAH THESE GUYS GOT MY BACK. They seemed super chill and have been very customer friendly every time I go. Shoutout ernest for hearing my compliment and juan for putting those pickles on love those guys. read more

I don't know why I continue to give this location a chance. They have management that just don't care. Once again I had an awful experience at this location. Ordered the new grinch meal and waited forever. Finally someone comes out to tell me they ran out of the socks. They don't offer any substitution for that missing item and tell me I have to call customer service for a refund. I refused to do that and they finally offered me a free happy meal toy ( not the same value ). I am once again kept waiting forever for food. Food arrives and they forgot my fries and sauces. Wait again forever and no apologies offered. No manager or shift lead came out to speak to me. I might add the car next to me had the same issue and he was still there waiting for food when I finally left. Get home a few minutes later and my food is ice cold. I had to throw the fries away. I am so upset right now. I spent $17 for a stupid grinch meal and don't get to enjoy any part of it. Nothing will come of this. They never respond or apologize. Management do not care at this location. I have written negative reviews before and nothing comes of it. Nothing improves. Next time I will drive over to McDonald's on valley where they actually care and offer solutions. I can't even complain to corporate because the girl didn't give me my receipt read more

Food and service are great and nothing less than what I expect from the McDonald's staff. I always receive the food hot and within a reasonable time. Gotta have my Big Mac! My one gripe, and I'm looking to see if this affects other Yelpers/customers, is the McDonald's APP. No matter what location I go to, the app glitches. I'm not sure if this is the WIFi at the store you visit, but no matter how good your cell connection is (Android or IOS), the app stalls. This is unfortunate because you gotta take advantage of the deals on the App. Badaba-ba-baa, not loving this app. read more

Ok, this might be a crazy take, but I think that the food at McDonalds is really good. If you were to strike away all the branding and lettering away, and tried to make the food stand by itself, it might make Michelin's guide. This Mcdonalds is clean, and the service is fast. No complaints. MAKE SURE TO USE THE APP TO GET ACCESS TO GREAT DEALS read more

I'm not sure if going thru the drive thru is any better than ordering inside..customer service is subpar. I suggest going to another McDonald's if you can. read more

This location is the closest to where I live yet the worst. The curbside pick up always takes forever. Most locations took 10 mins, but this location always took 20-30 mins, I am talking about just 1-2 meals. In addition, there were always missing items. Either no sauce for chicken nuggets, or forgot the apple slices for the kids meal. Hire someone who can do the job! read more

Food always cold nothing ever made fresh prolly the worst McDonald's to go to in surrounding area

This has to be one of the worst restaurants in the chain. Went through the drive through to save some time, but they took my order for a Double Quarter Pounder (no cheese) Large Combo meal... ok.. so they have to make the burger, so they tell me to pull in the spot #2. the next 4 cars also had to pull into the parking and wait for their order. I waited 15 mins for someone to come out and bring me my order. Upset, I left, and drove home... when I got home, I took out the Large Fries, and it barely had about half a box! WTF? if you're going to make people wait for their orders, at least serve them properly! If you don't want to be upset, then I don't recommend this restaurant. Not unless, you know someone who works here, them maybe you'll get "preferential" treatment. read more

This is my first yelp review ever. Every time I order from this location something is burned and inedible or part of the order is missing. Today it was both. They left out 2 whole sandwiches and the one that they did give me was completely black and burned. I don't understand who would even think it's okay to put this in the bag for someone to eat. I would avoid this location. read more

Wrote review in a rush. But yes. I gave them 3-stars because I was inconvenienced today driving through. The experience should have been more efficient but failed me today. I still gave them 3 stars was because they were willing to fix the issue and gave me 4 pieces of hash browns which I appreciated. But, Ok.....someone doesn't know what comes in a Deluxe Breakfast Bundle???? Drove through my order but had to return inside due to missing 3 pieces of hash browns.....they missed my favorite food????? Sheeesh. Come on, this is a Walnut branch, don't embarrass me.....you guys need to shape it up. read more

Came twice to this place and used the drive thru and they are extremely slow. They make all their customers park and wait for the food which takes forever to come out. Will not be back here. Only putting 1 star because I'm forced to. Booo read more

If you order for pick up or drive thru, makes sure you COUNT/CHECK! We ordered 30 hamburgers online , we got to the location, they claimed they don't have our order. We had to wait, then our order is ready. Good thing we counted, the bag only had 20! They claimed again that they are running short of cooked meat but I told the manager that they released our order, that meant the order is complete. If we didn't count onsite, I would have left with ONLY 20 burgers. read more

The food is good, however, we ordered 30 minutes before our meal was given to us. The workers had 8 orders shown on the Now Serving side of the monitor, one of which was ours. I expect timely service as it wasn't that busy, save for a couple cars in the drive -through. The workers seemed to be talking and laughing in the back rather than making the orders. We ordered one ten piece mcnugget meal, one six piece nugget and large fry, one mcchicken large fry and a small drink. I could excuse maybe 15-20 minutes, but the nuggets and fries are usually cooked in bulk, so I don't understand how it could have taken any longer than 20 minutes. Not only that, the worker forgot to give us our drinks. read more

I'm giving the place 4 stars because their ice cream machine was working and the workers were extra friendly when I visited. Obviously, the drive thru could be better, but being that this is a fast food chain, they do an alright job aft keeping things orderly. The smell inside is that familiar McDonald's smell, so if you're looking for consistency, this is the place. read more

It's clean and decent inside whenever I go and the staff is friendly. I don't usually order ice cream but when I do it's in the afternoon and there's no problem. I have ordered through app and chose drive-thru it pickup my food. The only time I have had an issue is when I choose to pickup at counter. It usually takes longer than just going to drive-thru or just walk in and order at counter/kiosk. Haven't had any issues with my orders so far. *knock on wood* read more
