The microphone on the order screen was not working, but none of the staff could seem to come out and take the order for us. Had to speak to 4 employees in total to finally get the full order taken. Just painful.

I went to Sonic about 2 years ago, not recent. The service was great, I could understand the person on other end, not speaking too fast, very clear. It was a very hot day, I could have gotten out of my car to eat at table.

Best shakes in town!!! We stayed in San Marcos for 10 days, stopped at Sonic 7x. Favorites are choc Oreo and strawberry cheesecake. Half price after 8. Need to have the Kevin Durant slushes too - so many to choose from!!! Kids enjoyed them. The onion rings are a must have!

There are 3 Sonics in San Marcos have been to all 3, but this one is closer to home so I've been here a lot. But I'm about to find the closeness not worth it. I have a basic order, order the same way every Tuesday. Consistently I have to repeat the order several times because the grade school dropout... More

I had the supersonic double cheeseburger. It was yummy! Extremely tasty, good quality beef, good size. The service is reasonably fast but very friendly staff. The fries are a letdown though - they need to improve the fries recipe asap! Having said that I would definitely eat there again and again if I could.

I have had good and bad experiences with this Sonic, including completely incorrect meals, resulting in a ruined lunch hour amid a long day at work. The food is pretty consistent, given that it is a chain, but always check your order and make sure you got what you wanted before you drive away.
