Sonic Drive-in - Harlingen

The food is delicious and the service is friendly. I have been a loyal customer for 5 1/2 years and still enjoy dining there.

Love the Cheeseburger and the muddy way to go sonic in Harlingen. I go every time I'm in Harlingen.

Had a chili cheese foot long hot dog. The hot dog was hardly warm, the bungalow was cold, there was little chili and the cheese was not even melted and I didn't get any onions. I was very disappointed.

The restaurant has great specials that you can always stay updated on by downloading their app. The food and desserts are always satisfying. I highly recommend trying the large chili cheese coney with tater tots, it's delicious!

I got some very fresh lettuce in my sandwich… The shake I ordered had peanut butter recess inside it’s supposed to be a strawberry shake lol but people make mistakes just hope the employees know when to throw out the veggies next time
