    I went to this sonic last night for a burger and a side of mozzarella, however when the young girl answered the speaker, she was extremely rude. After receiving my order and getting back home, I realized that they had forgotten my mozzarella, and when I called back to speak with a manager, the individual that answered the phone said there was no manager at that time.

    Jenny did a great job. I ordered a combo with a milkshake and ask them to wait and do the milkshake after I got done eating. She made it easy and I really appreciate it

    Ordered one small order of mozzarella and a slushie and it took 40 minutes to get my food. Would not recommend this location if your on a time crunch.

    This place is always understaffed. Don’t go here unless you want to wait 20 minutes for food
