Placed an online order like always and the lady on the mic sounded fine until I get to the window and she flings her hand up with her finger pointing to pull up to the end as if everywhere worse does it that way which they don’t. Then I pull up to the end for her to almost bring me someone else’s food so she had to go back to get my order. I get home a what do ya know no sour cream on the one taco I got so not only do they almost try to give me the wrong food but they still mess my order up first overall bad experience at this taco John’s usually the service is better and don’t have people working that clearly hate their jobs. The lady gave me my food definitely had a attitude for no reason told her thanks an didn’t say nothing back after being ignorant smh do better.

Too expensive. Use to come here all the time. My Daughter and son loves the soft shell tacos but for almost 4 dollars just for one is insane. I won’t be coming to buy tacos anymore.

Ordered delivery from this location on September 21, 2025 through the Taco John’s app. My order included a six pack and a pound with three sides of cheese sauce. Upon receiving my order, it did not include any of the six soft shell tacos with added tomatoes, only one of the two servings of potato oles, and one cheese sauce, along with the delivery being late and food cold.
I promptly called the restaurant and was advised by the lady I spoke with that she had “bagged the food” herself and it was there. I stated the food was missing and I had not received it. She then offered to remake the order but I would have to come pick it up or she could give me a refund. I advised that picking the order up defeated the purpose of ordering delivery and would like a refund. She advised she would process a refund. It’s nearly two weeks later and my refund has not yet been received.
I will never do business with Taco John’s again after not only being lied to about a refund, but also for spending nearly $60 altogether on food, delivery fees, and tip and not receiving the bulk of my order.

20 plus minutes in the drive thru for 2 tacos and a crispy chicken wrap. Takes longer than going to a sit down restaurant. Pulling around building to wait is ridiculous! This is suppose to be drive thru. Sorry taco johns I won’t be returning.

Love me some Taco John’s. Potato olés take this place to the next level. The staff is always very friendly and helpful.

What even is the point of ordering on mobile if every time I have to pull around to the parking lot and either wait or told to come in and get it. Even with no one else in the drive through.

Great food! Under staffed! Only 2 people working to work the drive thru and inside! Tables needed to be cleaned.

Service was a little unenthusiastic when asking them questions on the menu. My 8 year old says its a 10 out of 10. Definitely beats their competitors in taste.
