Ordered the same drink THREE times and each time they gave me the wrong drink and size I really dont think a 44 Limeade is a hard order to get correct so why am I receiving sprite with limes? Thats two COMPLETELY different drinks and their phones dont work when you try to call and get your order fixed 0/10 would not recommend

This place is trash please people stay away from this place my sister and I ordered food from there as separate times but the same day and she had a hair in her food and my daughter had a hair in her food so disgusting. The staff is rude as hell nothing but young kids that don’t give a shit about people and their food all they do is mess around and talk about partying with each other. They need to bring in people that does their job right that value people and the food this can make people very sick!!!!!!

I bought a burgers meal and I opened my box and my burger was all wet soggy ! So was My box wet and soggy it was not good experience lettuce’s was soaking wet I think the workers need more training on making the food !!! If you want people to go back food has to be good and made with effort

I ordered a cheeseburger some drinks and sides at 4:30 through the mobile app. The burger had too much sauce on it. I couldn’t eat the burger as all the sauce made the bun soggy. I called for a refund and they said without the receipt they couldn’t issue a refund. I told them I wasn’t handed a receipt as it was a mobile order and I just have the confirmation emailed receipt available. They said that wouldn’t work and they could not issue me a refund for the burger. Just to be clear, I was not asking for a refund for the whole meal, just the soggy burger and I made that clear over the phone. Everything else was great. I’m a little dissatisfied with the customer service.

On Sunday November 7th, we placed an order through the drive-thru for three kids meals and a garlic butter bacon burger combo. When we got to the window, the cashier was being super rude. We asked for ranch and straws and she refused to give them to us. She was in the restaurant alone at the time. We showed her how the fries were almost empty and that it was unacceptable and she said “that’s how they come”. We stayed on the drive through asking her to give us our refund and keep the food and she said she was having the cops remove us. We asked for a manager and she said she was the manager. We threw the food away in the same drive through because we didn’t get what we paid for and we showed the police officer that we threw it away. A case was opened for this incident two weeks ago through their corporate office and I have not received a call back. It all makes sense of why the managers are as nasty as they are to the customers because management doesn’t care about the customers and what the employees are doing. I’ve been asking them for a refund because of the incident and the dog being thrown away and I’m yet to hear from them. I have a video of the terrible experience and I cannot upload it. 🙁

The food was OK but extremely salty. Not sure what else I expected, but it’s good every now and again. There are definitely better fast food places though.

Today was a busy day for Sonic and there was only 4 people working rushing to get order in. The food came at a good time frame but it was burnt and the burgers were dry. Lack of management I guess. Fries were good and great ice tea.

Food was okay, I have had better the fires were not fresh. However, the customer service was great and had the typical sonic atmosphere.

Went in today for a quick brunch for me and my 3 kids since no one was in line I figured it would be quick since i was in a hurry. I ordered right away and got to the window. I paid and then I was left sotton and waiting for about 20 mins. No the boy never came back to the window to let me know what was going on. Just sat me at the window. When he did finally come back at 18 minutes later. I asked him what’s going on and what’s taking so long. I needed to leave. Please talk to employee Elijah and let him know that it’s very bad customer service to not communicate when things are taking long we than expected. I was late for my appt thanks to this hold up. I would have just asked to get refunded if it was longer than 10 mins wait time. Jut very bad customer service. He also just loked at me like I was stupid ad didn’t speak again. I’m writing this in hopes that you can train your employees better. I was the only car except for a car that pulled behind me after about a few mins time. Highly unacceptable. If you want us to give a good review like your window sticker then train and run the business better!
