Review for a featured item: 🍓 Strawberry Horchata Cream Slush🥤. I get what was being attempted, but I'd actually recommend to AVOID it. Or at least omit the Horchata flavor. It tastes like how a cinnamon apple candle smells. Barely even a pink tinge to it, even less strawberry flavor at all. Nice try, but no.

Dante was great! Brought the food and made sure I had my condiments and straws. Great job!

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.
