Ordered a Turtle Truffle Nut blast...it only had a 'sprinkle ' of the topping on the top and just plain vanilla under it. Not like a Blizzard which has it all mixed together. Will be my last time at Sonic...unless I'm in the mood for vanilla ice cream
We (are out of towners) went to get our Sunday evening munchies and after what felt like forever on the wait, our hero car hopper Valeria came to the rescue. Just by her shirt being mugrosa, we could tell she poured, her heart, and soul into our order. We are grateful for such a hero. Keep up the good work Valeria.
It was way too salty. Had 2 number 5s and 2 breakfast burrito combos with tater tots, all of it way incredibly salty. Almost inedible but it was expensive so we ate it. Probably will stick to drinks from here
