The food is good considering the price. I almost always use the drive-thru so I can't comment on the in-house staff.
The one re-occurring problem we encountered at the drive-thru is that we were often sent off with an incomplete order. All the food we ordered showed up on the receipt, so I knew it wasn't a matter of ""perhaps they didn't understand me when they took my order."" Almost always our order was missing something. Now, I sit there in my car and check my order to make sure everything is there. If it isn't, you bet I'm knocking on that window 'til I get my complete order.
The one MAJOR problem we encountered at the drive-thru was on a week night around 11pm. After I received my food from the drive-thru attendant I realized I had not been returned my card. I had not pulled my car away from the window yet so I got her attention and nicely asked for my card back, assuming she had just sat it down and forgot to give it back to me. She insisted she had given it to me (with noticeable attitude). I'm not a careless person...my wallet was in my lap ready for me to put my card back in it. I also did not receive a receipt, which is what they usually give you along with your card after they swipe it. I thought perhaps she had dropped it so I got out of my car in the drive-thru lane and checked the area between my car and the window. Nothing. I drove to the parking lot and practically tore my car apart looking for my card. It wasn't there. I'm not a messy person - I'm not absent-minded. It wasn't there. She didn't give it back to me. I went inside (and not with an attitude, I was very civil and patient) and asked the same girl if she could please look one more time. She walked over to the window area and barely glanced around for more than 5 seconds before she glanced back my way and told me it wasn't there, that she gave it back to me. I then asked to speak to a manager. The man who I spoke to only asked her to look again. I watched her look - a blind person could have done a better job looking. I resisted the urge to jump over the counter and look for myself, not mention strangle someone, and walked back to my car where I promptly got on the phone with the bank to cancel my card (and we all know how pleasant dealing with the bank is! lol). I haven't used my card at Taco Cabana since. Cash all the way. I don't trust them!
Pros: quick service, open 24hrs, most of the staff is friendly
Cons: Some of the staff are careless, rude, and lazy individuals.
