McDonald's in San Marcos, TX – Reviews, Hours, and Contact Details

The front of the worse Mcdonalds on I35!

Pico Guacamole sandwich, here with buttermilk chicken and artisan roll. I'd definitely get this again for under $5.

Yes, I got a McGriddle AND I REGRET NOTHING!!! Less than five minutes from order to exit. Thank you, breakfast team!!

Mushroom and Swiss burger had onion rings tucked in there, which I didn't expect. Tasty.

The mushroom and Swiss included surprise onion rings. Decent flavor, good textures, certainly filling.

Inside the Buttermilk Crispy Chicken sandwich; mayo was under the lettuce

Crispy chicken. First glance I wasn't sure it was worth $4 but it was indisputably more meat than I expected!!

White cheddar garlic sandwich: some garlic in the aioli, but it's the little fried garlic chips that may be too much for some. I liked them.

I'm not sure why the overall rating is so bad; I had a great experience. I went through the drive through about thirty minutes before closing while they were understaffed, and they explained to me...

Disappointing Experience - Cleanliness, Service, and Accessibility Unfortunately, nearly every aspect of our visit was disappointing, with the exception of the McRib. We arrived around 1:50...

Waited 30 minutes for cold food - then was told feels warm to me This generation is lost. Customer service is a thing of the past. McDonald's is dead - bring back the playplace so it's...

Not sure why corp is not all over this store. Has to be a bottom volume store. Poorly staffed
