We stopped here to pick up gift cards for teacher thank you gifts. After 20 minutes (and us calling back) they came out to tell us they were out of gift cards. I'm not sure why it took them 20 minutes to figure that out.
I've also had experiances of broken stalls, and messed up orders at this location.
We are HUGE Sonic fans, especially to head up for happy hour right after I pick my girls up from school, but we now go out of our way to skip this location.
