    It was my first time and that burger was so so good. I always seen your commercial but never went but last night I was tempted to go to Pork Chop BBQ but didnt want to spend that kind of money. Something said let's try Sonic and I am so glad I/we did and fries and milk shake was chocolate was delicious. I will come back when I'm in the area for sure!!! Awesome way better than McD's well I usually don't go to fast foods anymore but I will go back her again!!!!
