Tried the new churro shake. Vanilla ice cream with churro and cinnamon and sugar on top, i hope that's not the way its supposed to be made. Kids/employees on their personal phone, behind the counter, with gloves on and touching food, improper training and not clean. Also the route 44 cherry limeade had no cherries or limes in it.
Placed my order online and waited almost 20 mins with only one car in the drive through. When I finally got my food my cheese sticks were cold and my burger was luke warm. It's the beginning of lunch it makes no sense that the food wouldn't be hot.
Lime slushie good (yum). Ordered on app which is so easy but when at Sonic location there is no option for drive through. Also if selecting a small, there are no numbers posted on most of the stalls. Had to wait almost 15 minutes for a car hop to bring 1 drink...and yes had to understand and have patience that it was a busy time.
