I dont know what happened to Sonic. I thought it was just the location on Pecan but it seems even a simple slush takes 30 minutes to come even if there's only 2 vehicles in the lot. Its never been this bad but lately its absolutely unbearable.

Burgers don’t have good flavor and they give you very little pieces in the blast, save your money and go down the street to DQ.

So I ordered an Avalanche and a slush, and it took almost 30 minutes to get them. While waiting, I could see the staff walking around looking confused, constantly checking receipts but not making much progress. I even got out of the car to wait by the door, but they wouldn’t acknowledge me. To make things worse it wasn’t even busy at all!! and they served other cars that arrived about 20 minutes after us. All that waiting just for a slush and an Avalanche! Definitely wouldn’t recommend this place.

Employees spend most of their time outside hanging out, talking and laughing and food takes forever to come out, just to have it come out cold. Seems like this is a hangout spot more than a work environment.

★☆☆☆☆ 1.0 Dani Pike · Aug 2025

There have been multiple occurrences where my order takes up to 25-30 minutes. (Even simple shakes or kids meals.) I’ve done mobile orders at this location as well, and upon arrival my order still isn’t prepared and takes an additional 15 minutes. There have been a few times where other customers get here after me, and I ordered and arrived before. It seems currently their drive through is out of order, I was there 20 minutes and never received a response. (If your machine isn’t working atleast be thoughtful enough to put a sign to make customers aware.) It seems that other customers have had a similar experience, and the issue should be looked into.
