Dumpster fire. We've been to this location a few dozen times and rarely do we not question our own intelligence for doing so. It's like drinking and then waking up with a hangover and saying, "never again!". But you go back anyways because the food is tasty and you are a stickler for driving. Besides all the sonics in this area are comparable. Epically slow, time moves backwards at times. We were once warned by an employee enjoying herself a good smoke to just leave, because it was chaos inside. Could be the worst managed joint in all of KC. read more

If there were a zero stars, this place would be the winner. My god, I have never in my life been so disappointed as I am with the consistently horrible service that this places provides. I have finally hit my boiling point and will never return to this Sonic again. I pulled up around 3:00pm today to get 3 drinks and waited for over 40 minutes. It took over 15 minutes just to get someone to answer the stupid red button then I waited 20 minutes before pressing the stupid red button again so I could ask where the hell my order was, only to sit for another 6 minutes until I finally gave up and left. I don't know if it is the staff at this location or if it is just the way Sonic is setup to operate, but that is complete and total bullshit making someone waste 40 minutes of their time only to leave empty handed. read more

Saturday morning 11/21/15 at around 11:30 my BF and I stopped in for breakfast before heading out for the day. The restaurant wasn't busy and it didn't take long to get our order; supersonic breakfast burrito combo, mozzarella sticks, and onion rings. However after we pulled out to eat on the road, I noticed there was fryer grease dripping, from the tots, then from the rings, then from my breakfast burrito, and the entire bag. It was obvious we were served/dumped an supersonic upsize of grease with our food. I was completely distraught that someone would intentionally do that to their customers. May God help this sonic get their employees on the right path. read more

Awful service, rude carhops, cold food. Probably the worst sonic I have ever been to in my life. If you would like to eat here be ready to wait for a long time. read more

I waited over 20 minutes tonight for two drinks. They were busy, but it was frustrating because the workers were socializing with a group of teenagers that were sitting outside and also walking in and out of the inside area where only the workers are. I told the carhop that I was frustrated with the wait time, and he walked off without giving me my change. When I called after him, he obviously heard me and ignored me. I asked for a manager, who offered to have James bring me back my change, which I was uncomfortable with because he was obviously angry. He instead brought me a free token for a medium drink but not my change. The manager was very apologetic and kind, but this behavior by an employee is definitely not acceptable. read more

Just went to this Sonic and ordered the cookie dough big scoop blasts. What a waste of money, the help is so bad and inept there was no cookie dough in the entire blasts and only the big scoop on top. So I paid an outrageous amount for medium cup of vanilla ice cream. Plus they tried to deliver it to the car next to me. I could drive to the Sonic in Spring Hill and get better service and the orders right. Won't be going back to this one. read more

Burger Luke warm, tator tots less than Luke warm, service slow even though not busy, last time here. Over priced for terrible food!

This is the worst Sonic I have ever been to. It took almost 5 minutes to order. The popcorn chicken was soggy and so were the mozzarella sticks. We asked for ranch, and they never returned to give some to us. One positive for the place is that the workers were friendly. read more

Service is terribly slow. Food is cold. We give Sonic a try once a year and each time the wait is terrible and the food is awful. Staff was inattentive and non-responsive. Car hop promised ketchup and a knife and never came back. Shakes were not well mixed. Fries cold. What a crappy place. I used to love Sonic. What happened? Avoid. read more

S-U-P-E-R slow! It took 15 mins to get my order the first time - and it came out cold and missing several food items (hard to do when I only ordered a chicken strip dinner - but they managed to skip a chicken strip and the onion ring). The food I did get was cold! I asked them to remake it - and they did. 10 minutes later (almost 30 mins after I pulled into the parking lot) I was leaving with food. This time I didn't even look at it until I was home - the chicken strips were all there, hot tater tots, and an onion ring. However, the gravy is like water with a few chunks of flour floating around in it. If there was an option to give "0" stars - that would be my rating for tonight's service. read more

Today is the last time I try this Sonic. The food has been mediocre before, but today was the worst. Burger was lukewarm and bun was stale; the tots were cold and tasted like they were cooked in rancid oil. read more

If I could give zero stars I would. I have been told on numerous occasions they are too short staffed to take my order or like today I was told if I wanted to place an order I had to wait 15 minutes and then I could ring back in for an order. This is the worst customer service and very annoying. The management here needs to step up and make sure their customers are being taken care of. As you can tell from most reviews this is not a new thing. Get it together sonic! read more

Sonic on 151st and Blackbob. Stay away. horrible service, let me rephrase that. no service. I waited 12 minutes with no one answering honking didn't help. Not the first time. So my advice if you want to get ignored and see what its like to be invisible you can do this at this sonic. read more

Ordered three slushes, received what can only be described as 3 waters with flavoring. When we told them what was wrong they said sorry and after a long pause that their machine was broken...no shit? This isn't the first time it happened this week so they are selling their slushes without letting people know the machine is broken. Secondly when we asked for a refund the first person ignored it, the second person said some very quiet words and finally the third guy was helpful. I don't blame the workers but whoever instructed them to keep selling them without telling the customers. I don't know what happened they got really good not too long ago and it all went back down. read more

This is by far the worst Sonic on the planet. It is so close to my house and I have had nothing but bad experiences there over the past 10 years. They were once completely out of meat (yes all meat); they once sold me a shake that was completely melted (knowing their machine was broke); burnt food; long long waits; and once they never took my order after a 10 minute wait. These are just a few of the bad experiences. I love Sonic, but don't go here. Drive up to 135th and Black Bob. You will be happy you did. read more

Horrible service and cold food. You would think after waiting 10 minutes and having to repeat your order three times but the idiots at this location will get your order right. But evidently I'm Giving these idiots too much credit. I thought the McDonald's across the street was bad the sonic by far is the worst sonic in Kansas City. Unfortunately I can't give them a negative star have to give them at least one. read more

Worst fast food restaurant in Olathe. I'm not sure how they remain in business. My wife went to pick me up a foot-long coney. She came back with a bare hot dog covered in just onions. When I called the establishment, a young man answered the phone. I didn't believe him at first because he sounded so young, unprofessional, and totally nonchalant about my concern. He said that I could come back sometime in the future and just get another hot dog. While speaking to him, I was also reading the Yelp reviews, and told him that customers receiving wrong orders seemed to be a common occurrence at that location. He then became agitated and began to speak to me indignantly while also raising his voice. I then asked to speak to his manager and he refused to give me their name. After repeatedly asking, he told me that he was the manager. He stated that his name was Isiah Maldonado, and claimed that he was the General Manager. I then asked for the corporate number. I called and found out that it was a bogus number. I then had to call back and he gave me the actual number. After calling corporate, they told me that the location was owned by a franchiser and they've received numerous complaints before. They guaranteed that they'd contact the owner and voice my complaint. They were very professional and polite. If you read through these Yelp reviews, you'll find that many orders are taken incorrectly because English is not the first language of many of the employees. They can't understand what you're saying and don't bother to take the time to make sure they received your order correctly. read more

I've been to the Sonics in Lawrence and thought they had about the best fast food hamburgers around. Unfortunately, it's not the case here. There was something about the hamburger that was off, I'm not sure what. The fries were good as was the service (however, minimal). A hamburger (which is charged like a cheeseburger without the cheese) and fries was over $6--as much as a much better sandwich elsewhere or a lunch special at a sit-down restaurant. Maybe the fact that they wanted to charge me 39¢ for water left a sour taste in my mouth. read more

This is the SLOWEST service I have ever experienced! Definitely not FAST food. Its competition across the street has Golden Arches. Next time it's across the street .Food was cold when it finally arrived. read more

Absolutely horrendous service at this sonic I only go here if I have absolutely no other choices. I've showed up at 3:45(a few times actually)and didn't get acknowledged until after 4:00 and the servers along with the managers refused to grant the happy hour price I should have gotten. It's an atrocious business; frys are always soggy, the servers have zero people skills, and it's been like this for years so clearly nobody is going to do anything about it. Your best to avoid this sonic at all costs. read more

This is the WORST sonic we have ever been to!!! I was hoping they had an off night but my husband and I gave them the benefit of the doubt too many times. We have been there 3 times now and waited almost 20min for milk shakes! Not only did we wait insanely too long but the shakes were HORRIBLE!!!! They were melted and disgusting. We asked them to remake them once and they were very rude about it. We won't be back! read more

I rarely review places negatively. But just wanted to give others a heads up. Today was $0.50 corn dog day and I ordered 5 corn dogs for my family. After preordering on the app and waiting an extra 20 minutes for the food to arrive, I finally got my order. Because my kiddo had been super patient and was extra hungry, I tore open one of the corn dogs to cool it off for him and it had uncooked batter on the inside. (Thankfully I didn't blindly given it to him!) I opened another and again, raw batter. So I let the attendant know and she was nice and went and got me 5 new ones. I checked those. All raw batter. I didn't have time to wait for this problem to get sorted out, so we left. And again, they were only $0.50 each but still a nasty surprise to bite into raw batter. I had hyped my son up for our special Sonic corn dog day all week cuz it's a special treat to get fast food and Sonic's corn dogs used to be one of our favorites. So we were pretty disappointed. Plus this location must be having issues because their service is really slow. I preordered on the app 7 minutes before I got there. Then had to wait 20 minutes after checking in to the stall. read more

No stars should be option. Service is terrible! Management needs to look into what problem is! Waited over 10 min just to order... Left. ... read more

This Sonic is awful. My wait was so long today I assumed they had completely forgotten about me. When my food was delivered I asked what the hold-up was. She mumbled something about having a lot of orders. The parking stalls were empty and the drive through had one car in it. I got home and discovered no salsa in the bag for the breakfast burritos I had ordered. This is not a one-time experience. Long waits, messed up orders, apathetic employees are the norm here. Even though this one is close to where I live, it will be faster and less irritating to drive up to the Sonic near 135th and Blackbob like the other reviewers have suggested. read more

I wish I could give zero stars. This is the worst Sonic (or maybe fast food restaurant) EVER. They hire people who don't care about being there. The employees smoke and then don't wash their hands before they start working again- and when you confront them a manager does nothing. Orders are always wrong, even if it's 2 drinks. SLOOOOOW. We have been probably 30-40 times in the 5 years we've lived in the area and it's consistently terrible. We now go out of our way to go ANYWHERE but here. read more

All I ordered was a sausage, egg & cheese toaster sandwich. I was on my way to work so didn't check it (as I normally do. What I got was a "small bun" (the size of a small sausage)with a burnt sausage, very little cheese and a regular sized egg. Needless to say I didn't get to eat. I took it back and had my money reimbursed!!! In order to post it says i have to add a star. actually this deserves a negative star rating!!! I Won't be going back!! read more

Super slow service! Waited for 20 minutes for a cherry limeade and a sonic blast. They had the AUDACITY to bring my order without drinks and say that they'll bring them right out and then completely forget about them. read more

The employees here are completely unprofessional. Instead of working they spent their time hanging out with their off work friends in the parking lot. Yelling obscenities in front of children and acting like they were not on the job. read more

By far the worst Sonic I have ever been to. I sat at a stall for over 10 minutes with no response. I then pulled up to the drive through behind another car that waited 2 or 3 minutes with no response at the drive through who then drove off. This is not the first time I have had problems at this Sonic and ever time I come here I regret it. Although this is the closest Sonic to us we will be driving the extra couple of minutes to the one down the road. This place needs a serious overhaul in management. read more

I wish you could give zero stars. This has got to be the worst run franchise in the history of sonic. Sonic should be embarrassed to have their name on the building. There have been a few times we've regrettably tried this sonic by my house. Tonight, my wife went to get two drinks, just two drinks. There were only a few other people there and 20 minutes after her order was placed she hit the buzzer and was told it would be another 15 to 20 minutes. She then cancelled her order because they didn't know what it was. We will never got back to that sonic and I'm tempted to never go to another sonic again because they allow that place to stay open. It looks like I'm not the only one with these opinions according to the other reviews. read more

Don't go to many fast foods places- but I have to say that our experience was great! Very busy place, so had to wait a bit just like other restaurants - but our server person was cheerful and the gal who took our order was very friendly! read more

Worst service ever. Unfortunately only sonic nearby. Guess culverts and other places will get my service
