Cruise on over to us at 509 Ed Carey Drive for the ultimate SONIC experience!
Change back your big meal deals to include chicken again, that was the main reason I went to sonic. Not going again until it's brought back.

This sonic is always spot on - we occasionally go to others if we’re out of town or traveling and quality varies. Not at this location can always count on good food and drinks and friendly staff at this location - props to the whole team there.

Wanted a cream slush but in the app there are only basic flavors. I pushed the button to ask if I ordered a cream slush if they could change the flavor. Was told it might be a different price. I asked them if they could check. He said u can just order here. That was nor the point I was trying to order all drinks together for everyone in the car not seperate. FYI the price was the same.
