- YHYasmeen HussainMay 12, 20261.0If I could give zero stars I would. I ordered a hot fudge sundae and they barely put any fudge on it. I was told it was an extra charge which I understand McDonald's will nickel and dime you for every little thing which is whatever fine. I do not mind paying extra for something but I wouldn't have to pay extra if employees gave the normal proper amount of fudge. I'm not one to argue over something small so I paid the additional 40 cents for "extra" fudge. But absolutely absurd that employees don't even give the proper amount and I'm made to look like the jerk for asking for a normal amount of fudge to begin with. Attached are pictures before the additional fudge was adde. Different angles to show how there's little fudge. So next time I'll just go to a different location.
- RTRachael TorresMay 3, 20263.0I simply asked for a number 4 the lady taking my order didn't understand I wanted the meal? Thats what ordering a number is. If I wanted to order everything separate I would. I wanted to change the folded egg to an egg round and she couldn’t understand that either. I hate to make it about speaking english but not getting what I ask for is getting tiring. Sticking to the fremont locations.
- ARAndres RinconApr 12, 20261.0They are so slow here.
- HRHenrique RamonesMar 28, 20261.0The service is terrible: they always get the order wrong. They make you wait in the parking lot for your food, and—to top it all off—they don't even bring it out to you; you have to go pick it up yourself after waiting 20 minutes. And, to top it all off, they always hand me the wrong order.
- KNKrista NalleyMar 22, 20261.0This mcdonalds makes me park in the parking spots outside the restaurant when I had placed my order in the drive through. It happens every single time I come no matter if I place my order on the app or in person at the drive through. They make me wait over 20 mins. Such bad service like foreal. They do it on purpose, and they cheat their drive through times. The workers are as equally passive and literally just don't care.
