If you’ve ever been to a Sonic, you know what to expect. While it is fast food, there’s just something nostalgic and simple about the way they do things. A multitude of options including chicken, burgers, hot dogs and all sorts of other snacks but you will find on the menu. A myriad of ice cream options and frozen treats as well. Payment is a little easier now because you have the option to pay right through the screen, but it doesn’t always work. I suppose nothing is perfect. Most of the time the service is pretty good, but at this particular visit the car hop seemed annoyed that we were there. I asked for ketchup and she said it should be in the bag if you ordered fries that did not bother to make sure there was ketchup. There was, in fact, no ketchup. I also had to ask for forks and spoons for a chili cheese coney and ice cream. I still tipped her because I know that they rely on those tips, but at the same time I wish her attitude about what she was doing had been a bit better. Even my small kids in the back said, “What was wrong with her?” The service on this trip won’t preclude me from going again. I love Sonic and it really takes me back to a time when I was young. Side note: I love the new crinkle fries!

Another 1 star for this place, obviously the coworkers think it’s okay to close early and put everything away instead of having items ready to order. Drove 30min away just to find out that items arent being served. Not what I expect, I expected a fast food spot with a full menu to have every item available. Strongly dissatisfied, to make it worse lady in drive thru at night can’t even explain basic literacy and solve an issue. Anyways they are more concerned with closing than working. At this point, all this cleaning supplies and soap.. I don’t even feel comfortable ordering knowing there’s a strong possibility of cross contamination. Please TRAIN YOUR EMPLOYEES and check if they even have their FOOD HANDLERS LICENSE. Basic 101

I ordered 3 slushies for pick up at 7-7:05 pm. We arrived at 7:10 and the app said that it was already completed and would not let me check in. We waited there for a long time that my husband had to get off the car and asked inside. It’s 7:26 and they gave our drinks all melted down. This place really sucks and they can’t even get a simple slushies order right. They didn’t even try to renew our drink so it’s not melted after waiting for a long time having our drinks just sit there. I highly don’t recommend this place. If you want sonic just go the the Lemon street one and not Placentia street at fullerton. This is not the first time they did this to our order and honestly i think it should close down.

Steven had the worst customer service ever! Definitely needs a refresher in customer service. Reached out to corporate and spoke with Dutch to file a formal complaint. He was pleasant to speak with and was offered a burger. Will be back to redeem. Hopefully it will be a better experience to revise.

My mozzarella stick is empty. That’s enough for a one star review, but everytime ive ordered groovy fries, each fry was very short, some were hard, and others tasted slightly undercooked. Otherwise, its slightly cheaper than some other locations, but empty mozzarella sticks are unforgivable.

I think the most fun experience here is pulling up in the drive in stall and eating here. Make sure you have your extra napkins. I’m not really a fan of their burgers, but they’re hot dogs, tater tots, shakes and drinks are fantastic! Service is fast n friendly And this time we tried the chili cheese.. it was great with the hot dog and tots.

we ordered with UberEats because we were very hungry and have no possibility to go out from the college. The order was supposed to arrive at 1.05am, but it arrived more than 30 min later, and the food was all cold.
After this, we opened the burgers and we noticed that all 3 of them were wrong:
-pickles missing in the first
-cheese not removed in the second and my friend couldn’t eat the entire burger because of that (paid addition of tomatoes was missing too)
-in the third sauces and paid addition of tomatoes and bacon were missing.
We called the restaurant, but they were like “there’s nothing we can do, it’s not our job to bring you new food.”
They acted rude, like they don’t care and it’s not their fault, and I found the whole situation really disrespectful to us. They told us to ask for refund on the app and come pick your food on another date, but we needed the food in that moment. They didn’t try to fix it and we ended up eating nothing or something different from what we paid at 2am.
You have really work hard to do such a big mistake like that and acting annoyed when the client is complaining.

This is our 2nd time eating Sonic foods, 1st was before pandemic. The foods we’re nothing special but they’re edible on both times & the staff were friendly with good service. It’s the nostalgia of eating a quick meal out of the norm.

I’ve had nothing but problems at this sonic. What in the WORLD is this bacon???? I only went to sonic today for mozzarella sticks, and for the SECOND TIME they didn’t have marinara sauce, like not having ketchup for fries. So I ordered this burger as a hail Mary to not waste my time. And holy crap dude, I want my money back
