Unpopular opinion after reading reviews, but we have had decent service and delivery when it comes to our orders at this Sonic. Very conveniently located to Fort Leavenworth. We do not often do fast food unless traveling or someone aka mom is sick and can't fathom dinner. We use this Sonic for treats and once I have gone for the wacky pack Wednesday special for my toddler. I have never had an issue with an order and everything has always been exact. Love the location to post and it makes it an easy choice. read more

I'm genuinely so passionate about this sonic it's not even funny. Idk what these reviews are about because this sonic has always been genuinely top tier food and service. they always make my order PERFECTLY even with complicated drinks. and the people are genuinely so nice also. I almost take all the bad reviews personally cause I fear I have a parasocial relationship with the people who work here. whether drive thru or mobile order...they pop their ish every. single. time. don't let the haterz get you down north sonic employees. the South 4th street sonic in this town is str8 GARBAGE!!!!!!!!! if you always want an absolute terrible waste of money and food I suggest going there. I wouldn't even give the South sonic food to a homeless person cause that would be so disrespectful. ANYWAYS, TRUST this north location is the shiz 27/8. read more

Really great food and fast service. Would absolutely recommend this place for sure. Really good food.

RAW HAMBURGER MEAT!!!! So gross, be careful when you eat here. I usually put up with the bad service because they seem mostly young, but this is just disgusting. read more

Absolutely fucking terrible. What smart one grabbed these tenders and decided to cook it. Then some idiot packaged it. An here i am staring at a "chicken tender". Bruh i couldn't even enjoy anything since ALL 3 were like that. How this even got COOKED is beyond me. Normal apology from lucas that also offered to remake it but im not driving back bc what the hell do i look like. wrong sauce, rude ass on the headset. just go to lansing. read more

Used the drive through twice with my two co-workers on the last 3 days. All of our meals were good, service was timely and the price was right. Nothing to complain about minus the food wasn't that great. Typical fast food but that's why you come here, right? Good location just outside of base and across the street from a major hotel. read more

I stopped in for a Route 44 Dr Pepper which as always was just the right off the charts in terms of syrupy goodness. The wait was a bit long as there were only two cars in front of me tho, and I forget how much those Route 44's cost unless you buy them during happy hour. Still a nice treat now and again so I'll be back the next time I need a fix. read more

horrible service and disgusting food!!! forgot 1/2 my order. chicken strips burnt so bad we couldn't eat them. worst of all there was pubic hair on my coney dog.... for only have 3 customers total you would not expect to wait 30 minutes to order.... Staff was more worried about dancing in the shop and snow removal than service. read more

I have to have a Sonic fix about once a week. Love the local Sonic in Leavenworth. Consistently good!!

The service at this location is horrible ! It takes an unusually long time to place and receive your order and the employee I encountered today was beyond rude . Do better Sonic read more

Prepare yourself for a Sonic boom of crap ... like a #2 Double Cheeseburger with Mustard ... appropriately labeled a deuce for being a turd of a burger. Honestly, it was kind of fun (and convenient since most regular Leavenworth restaurants were already closed) to pull into a Sonic parking spot at night and have genuinely friendly service bringing fast food straight to our car window ... until I discovered it was just really really crappy fast food. So, it's no surprise that this Sonic Drive-in rates as 2 stars for a #2 burger that tasted like number 2. read more

Got milkshakes here on a day trip from KC. Actually the best Sonic shake I've ever had, they were truly remarkable. 10/10, would highly recommend read more

I literally asked for cheese on a burger. i asked again at the window and she said, yep! no cheese. ordered four kids meals, and failed to give me the juice boxes. Rough place. Rough. read more

DO BETTER! Wear masks! Disgusting and Scary during Pandemic I saw employees handling & breathing on food; and breathing/talking without social distancing inside small building amongst themselves. Employees lied openly about their policy on mask-wearing: they were NOT required to wear masks while indoors preparing food & within close contact with fellow workers. Owner & management team do not ENFORCE mask-wearing. Address: 1000 N 4th St, Leavenworth, KS 66048 None of the workers have been vaccinated. read more

This place is trash!!! haven't been here in over a year but tonight I decided to give it a try. Ordered a number one with no tomatoes a large fry. I went straight home, which took me three minutes and by the time I got there and opened everything up. My burger was soggy with mayo all over the outside of the bun and the wrapper. The fries were soggy and cold and hard. How hard is it to get it right? Pathetic read more

today I order two drinks, one with no ice and the other with less ice. THe second one came with a cup full of ice and almost nothing to drink. Not happy!!!! read more

Whoever cooked the food on September 14 at about 10:30 pm the tots were hard and over cooked had NO flavor once so ever and the rest of my food tasted like it was used to wipe their ass. Dry, disgusting, and I feel sick. read more

Kathleen is so personal and sweet! Love seeing her at the drive through and having a quick chat with her.

Went the sonic in Lansing Kansas and had the best service I've had in a very long time. Kathleen was by far the nicest person I've ever dealt with in a drive through. I usually avoid this sonic due to poor customer service but after today you have won my business back. read more

Waited 20 minutes for breakfast, in the drive thru. You can tell the employees aren't happy and it shows. read more

I ordered a sausage and egg breakfast burrito today and it only had two, maybe three, really small pieces of sausage in it. Considering how much they cost this is ridiculous. The orange juice also taste really watered down. read more

This sonic is awesome. The service is so good, they take their time getting our family of 5's order right every time. They are so friendly, we love taking the kids here for a little treat. read more

We come here so often for the waffle cone ice cream. I give the snickers toppings and my husband is the waffle cone with strawberry toppings. If you just want a regular topping I would suggest you order the waffle cone and then a topping versus a special waffle cone and taking off what you don't want on it. They have a military discount which is 10% I believe. The little hot dogs and chicken sandwich is that our new I forgot the name but they're really good. The staff here always polite energetic and pleasant to speak to, and easy-going with transactions. It's located right outside the base which is very convenient for me and my husband when we have a sweet tooth. Of course I would love this place even more of happy hour was longer I always tend to miss the hours. Also if you sign up online at sonic with the email or some kind of account you get a free dessert on your first purchase. read more

I came back to Leavenworth after PCS and it's still the same. Horrible service. They didn't give me a straw or any silverware for my food. Disappointed again but not surprised. read more

Giving this Sonic 4 stars for the following- First, like all Sonics the food is cheap, bad for you, but tasty. This particular Sonic has great customer service as of late. The drive through line was backed up during an off hour- who knows why? I was stuck in it with a hungry kiddo in the swagger wagon; they actually came out to where I was in line and brought me half my order and even did the card transaction. By the time I finally got to the window, it was just a quick 'hand me the drinks' action and I was on my way. Very polite- fast service with employees willing to modify their own practices to make things better. A lesser restaurant staff would have continued snapping their gum and doing the process in a mind-numbingly inefficient manner. Good initiative, Sonic employees! You made a 3 star into a 4 just for that. read more

Ordered a real fruit slush, received a watery sweet drink, no fruit, no slush. And a Lil chickie, which is a small chicken tender, two pickles, mayo on 1/3 of a hotdog bun. They should have to pay people to eat this. read more

I give this Sonic one star as it needs some improvement. Not with the food, but with the staff. I have gone to this Sonic a number of times, only to have some troubling experiences with this one in particular. So i will list them accordingly. Incident # 1 I went to this Sonic and ordered my food and it came out in a reasonable time frame, the problem was when the young girl went to give me my change and handed me a fake $1.00 bill. I saw immediately that the bill was fake, as it was printed on white paper and did not look like the other money she was holding in her hand, and the ink was not right. I refused the bill and explained why, she shrugged and gave me a different bill. While i know a $1.00 bill is not much, but it was clearly something to me. When i got to work i called the restaurant and spoke to the manager and reported to him what transpired, he verbally blew it off. I explained the paper and the ink difference to him, but he seemed not to care. Incident # 2 I ordered my food for the lunch hour, the person takes the order, and then nothing. I wait 20 min. only to push the button again, this time i was told my order will be out soon. I wait another 15 min. and i push the red button again. Now i am on lunch break and only have an hour before i have to be back to work with my food and my co-workers food. The person came on, after pressing the button, only to get mad when i asked again where my food was. The person told me they had no order for me, so i had to re-order my lunch food and hurry back to work. I know they employ teens and young adults here, but i was disturbed more about the fact the manager on duty did not care enough about the staff passing phony bills out to customers, then anything else. read more

Used to be good at getting orders right. But the last couple months they stink! My orders are wrong. The bacon cheeseburger has maybe a crumb of bacon on it. Get it together man!! read more

I absolutely love this sonic! Everyone that works here is super sweet. Sometimes they get my order wrong, if I order from the app, but they never hesitate to fix any mistakes. read more

I don't care what anyone says, Sonic has the best hot dogs and cherry limeade. The teenagers that work at this particular Sonic are awesome; they hustle and are very friendly and respectful. Reminds me of a simpler time with a side of nostalgia. read more

No meal mix ups, but the food and service are less than average. Lowest rated sonic I have ever been to. It's ok if you don't have the extra 3 min to get to the next one down the road. read more

They have screwed up 50-60% of all the orders I have made here. Theyve given me entire orders wrong and missed items that i had ordered. They have also given me items that i ordered, but not to my specifications (like a hot fudge Sunday becomes a cherry caramel Sunday). They have also double charged me for two meals because I paid at the drive ins and then the car hops came out with a bill and when told that I had paid automatically said it didn't go trough even though it did. Skip this Sonic and go to the one a mile-and-a-half south. read more

I went to this restaurant two days in a row because it was so great. Excellent customer service. Food was fresh and tasty. Speedy with car delivery. read more

Your standard Sonic, decent burgers with friendly service. If you're looking for a burger, tots, or a shake it's worth stopping here.

Awful Sonic! Was in Leavenworth and my family and I decided to stop and get some drinks and tots from here. First thing that was bad is when we were getting our order taken everything was wrong and we told the guy and nothing changed. Then we sat at the sonic for a good 15 minutes before we even got our order that was half wrong. We had order a Coke Zero, Lemonade Slush, Diet Cherry Limeade, and a large tots. But instead of our Diet Cherry Limeade we got a regular limeade which is just too thick (from the syrup that is why we get the diet version) and then we got a medium French Fry. Wrong orders, slow service, and no other car hops besides 1 rude guy. Will not be visiting this Sonic again. Will just have to wait until I come home to go to the Tongie Sonic. read more

Great food, prepared quick, the right way. No complaints at all. I would recommend this place if you want a good burger. They have a lot of drink choices most all of which look good. The strawberry slush is a good, has fresh strawberries! read more

A lot of our food was missing. The lady on headset sounds like she's dead and she kept talking over me!

Orders are not delivered in sequence they are received and watched a Nother order gets placed after mine that was a full meal and mine was just a single sandwich but yet they received theirs long before I received mine read more

I ordered a small Butterfinger Blast, small M&M Blast, and small Banana Malt, and had asked for a military discount. The order took almost 15 minutes to arrive. The stall on the receipt was listed as ''??'' and I saw the carhop wandering through the lot to find the spot. When I asked about a military discount, he was unaware of it, and by that time I did not feel like trying to ask for one if it was going to take as long as the order did. The carhop did not have straws, and after asking for one, took another 5 minutes for the straw to arrive. I realized I probably should've not asked for one if I had known the wait was going to be another 5 minutes. Finally, the malt powder and bananas had congealed into a single lump at the bottom of the malt cup, so I assume it was not mixed in. This is the second time I have had slow service (the first was about a year ago) on a drink-only order at this Sonic, but it is VERY unlikely I will come back to this Sonic again based on this experience. Others, maybe. This one, no. read more

The food is fine, service is slow and they lie about not Sonic slam bags. If you're going to participate in Royals advertising then stop lying about the bags. read more
