Waited 20 minutes in the drive through for 1 sub when there was only 1 customer inside and no other cars in drive through and multiple people working. Crazy wait time for 1 sandwich.

The associates provided excellent customer service, friendliness, and they were also very helpful. This is my favorite Subway location in the Siouxland area and that’s why I keep coming back time after time.

The past few times I’ve been here the bread has been insufferably hard and dry, as if they are trying to avoid waste and not throwing out old bread when it is due to be discarded. They are going to have to do something different if they want to stay afloat with both Jimmy John’s and Jersey Mikes within walking distance of them now.

I bought a philly cheese steak from this store on 11/24/25. I brought it home and ate it, but it tasted funny. I figured it was just Me but later that night I started getting sick and today I'm really sick with nausea and vomiting. I called the store just to inform them their steak is no good and the lady that answered the phone said " I don't know how that's possible." I was a little offended because the sandwich tasted funny and I got sick. I just hope they take care of the steak before they serve it to someone else.
