    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.

    Smasher burger? Nah, ten pounds of grease till your bun is paper and tomatoes feel like a wet napkin! Terrible burger, terrible wait for terrible food, just overall terrible.

    The most ANNOYING place to go. I placed a online order and then proceeded to have to wait 20-30 mins when I showed up. This was not a big deal as I could see they were very busy. When we finally got our food the 2 large sodas had no carbonation. Annoyed we went to a spot to place a order and pressed the button. We proceeded to wait ANOTHER 20 minutes before anyone answered us. Once someone finally did we were able to ask for sweet teas to replace the sodas. Took another 5-10 minutes for that to come out. Once I tried it... UNSWEETENED TEA 😭. I had to call them again for them to bring a SWEET TEA. when they brought out the next one I thought surely it must be correct. Wrong another unsweet tea. I saw the guy pour our drinks was the one who we talked with. I think they just did not put sugar in their sweet teas today. So annoyed as I came here directly after work and now I have been off for a hr and a half and still have not gotten to go home.
