    Was not too busy, but still waited around 10 minutes to order from a stall. Once ordered, food was ready in about 5 minutes. I had stopped going to sonic about a decade ago, as their quality really went downhill. That said, I was really impressed with the burger, and especially the tots this time. It was a very good food experience overall. Will be going back.

    Seriously waiting in the drive thru for a bag of ice for 10 minutes. The person in front of me still hasn’t received their order. I only come here for the mini ice pellets. Worst sonic ever so far. Unbelievable now there’s 3 people behind me and one still in front of me. Super slow Sonic.

    Visited today and was disappointed with the service. I ordered a large Coke Zero with sugar-free cherry and vanilla, but was given a medium Coke instead. Even after I explained I had asked for a large (and repeated it twice when ordering), the issue wasn’t corrected—apparently, I was rung up for a medium. Unfortunately, this isn’t the first time I’ve had problems here. The wait is always long, the staff are not very quick, and my orders are often incorrect. Overall, the service continues to fall short of expectations.
