We had to stop by this place for a large order for 6 people since we came back late from a long trip. And so we ordered to give sonic a try. Yes yes, we were expecting greasy food, so we ordered dou ke sonic burger and all the addings, chicken tender, chicken sandwich, fries and drinks. The burger was ok, not impressed vs in & out, the chicken for both the tenders and sandwich was overly cooked and dry, guess they must've left it in the fryer wayyyyy too long. And since...
July 2025
It was a long wait to get the food and it was really busy. I pressed the help button multiple times and it took such a long time to get our order. However even though the food was expensive it was worth the wait and tasted delicious.
July 2025
I wish that Sonic didn't have such misleading signage and advertising. We have more than once been drawn in buy a special, then get to the window and find it is not actually on sale or whatever and it cost much more than we expected. The Smash burger is amazing.
