So bought lunch right when it changed over to 11am on Sunday March 1st 2026. When my food go here about only 20 minutes. My fries were completely cold and shriveled. Soagy too. So how does fries that were made probably about 10 minutes before 11 be so disgusting. They should have been still way more fresh than that. My Mcdoubles were so salty and I couldn’t even finish them. My shake was so watery. What’s going on at this location. I knew I should have tapped on diamond bar McDonald’s on Golden Springs and Brea Canyon on Uber Eats. I never get anything awful from that location. I only chose walnut because I live in Walnut and I was trying to give the business to your location. Sorry I won’t be buying from you no longer.

The deluxe breakfast still a favorite of mine throughout the years. The eggs are cooked without any burned flavor, the hotcakes butter and syrup are a good combination, the hashbrown is crispy, the sausage and bacon are really good and finally, the biscuit is in my view, is the best biscuit within the fast food business. The coffee is good, but the orange juice is not, just OK. but the whole deluxe breakfast makes come back every time.

Honestly, I’m never expecting much from a McDonald’s, it’s a fast food corporation. But out of every McDonald’s I’ve ever been to, this one has consistently been the worst every time I’ve gone to it. Oftentimes staff forgets food, orders, etc. They seem understaffed with how unusually long orders take and how many times they’ve forgotten to put things in that me or my friends have ordered. Not the best, wouldn’t recommend going here unless you’re desperate for McDonald’s fries…

The guy with the tattoo below his right ear, I always see him completely engrossed in his work. A good man. Excellent people are always so dedicated.

Fast service. Hot food. Separate men n womens restrooms a plus. Drinks don’t taste watered down either. Clean place. Two stars off because the evening manager doesn’t know how to assist customers with a professional manner. Will try this place again another day. Happy eats everyone

I ordered a sausage burrito with picante sauce pack and bagel with butter. They made me go park in the waiting area for several minutes. No picante sauce and no butter on the bagel.

Order around 1pm yesterday and it took 20minutes to get my order. I probably would not have gotten my order if I didn’t say anything. I went up to the pick up shelf and the girl on shift with highlights wearing the safety vest gave some attitude when I asked about my order. I was going to say something else, but she turned around before I could say anything else.
It wasn’t until then did they start working on my order. I saw my order just sitting there and when they were assembling it they are working SLOWLY. Like the girl was getting my items one by one and walking back and forth instead of just holding the box and adding the items. The nuggets were basically cold, fries were whatever, and the sweet tea was warm. I did say light ice, but it was basically nonexistent. 10/10 don’t recommend this location.

thank you Alejandro for the help. He picked up his phone very promptly and answered the questions that I need. And he is very polite when answering the phone, although I did not intend to purchase anything at the meantime. However, I’m a regular happy meal customer.

They gave my mobile order to someone else in drive thru. The trash seems to always be full and tables not cleaned, even first thing in morning.
