The OG Oklahoma Onion Burger done right! Hands down one of the best burgers I've had in my 59 years on this Earth! Warm bun, perfectly seasoned beef and all the veggies! It is a small shop. Not a lot of indoor seating. But on nice days there is an outdoor patio. And they do stay busy! When near OKC, there are two places to go for the best burgers. Sid's in El Reno. And Nick's in OKC. Best burgers in Oklahoma. read more

Sid's Diner - Our Oldest Grand about to devour her first Oklahoma onion burger. - Diners Near Me - El Reno, Oklahoma

You can't beat an onion burger with fried and raw onions and cheese with a chocolate malted.

Absolutely incredible burger experience. If you're in the mood for a casual diner burger (OK onion burger of course), you're in the right place. Service is friendly and fast. I am counting down the days until my next visit. read more

Food was excellent! We had 2 steak sandwiches and an order of onion rings! Everything was delicious, the sandwiches were so big we should have split one! Service was very good, everyone, including other customers, were very friendly! You can tell this is a hometown favorite! Had been here before, this will become a regular stop! read more

A great burger spot along Rt 66 in El Reno. Indoor outdoor seating with a park like setting. Delicious food and huge fries per order.

We ordered our meal. The waitress asked us if we wanted lettuce and tomatoes on our hamburger? We asked if included? She said, "Yes.". My drink came right away and our fries. We then had to ask for silverware from another waitress as she left none. We then asked for a plate to put half the fries on as they were too hot for my friend to eat as he has very few teeth. The waitress didn't act like she had permission to do this so it took much longer than it should have. Then we waited and waited for our hamburger. I finally figured out she didn't place the order so we re-ordered it. She was oblivious to it--didn't even remember she had asked about cheese, lettuce and tomatoes when we first ordered! Then,, we got our bill. We had been charged the extra for the lettuce and tomato. We notified our waitress and another waitress took it to the manager. We overheard the new waitress lie that we knew there was a charge. The woman cook manager came over and didn't even listen but pointed to the menu. I then stated calmly, we even had to wait on our hamburger. I said, "If you don't want to make it right, we won't ever come back." She got angry and chased us out the door and said that was fine! It was obvious she was uneducated. I will never go back until they have hired a new manager and train their waitresses better! I think they think they don't have any competition! Go next door to the Mexican restaurant! read more

Well... when you think you have found your favorite spot for a burger, and then you run into THIS!! MEAT the chicken fried steak sandwich at SIDS! Oddly enough, the owner was talking with his meat supplier when I walked in, and I got to pick his brain about the meat. All I can say... (without giving away any secrets.) ALL the meat is fresh and never frozen... THAT'S ALL ILL SAY. Most places buy pre breaded frozen steaks. NOT HERE!!. This is a fresh not frozen, large, cubed steak, ran through an old-time tenderizer, then hand breaded. Well seasoned and super tender. Give it a try! It's my new favorite read more

This is an American burger institution, so we had to try it on our way down to OKC (a little out of the way, but not by much). It was pretty empty when we arrived, but the place has an overall cozy vibe and very friendly workers. We ordered the famous fried onion (depression) burger, a cheeseburger for our daughter, a large basket of fries, and a side salad. I think we're perhaps the first people to order a salad there in 50 years because here's what came out: shredded iceberg lettuce (like you would put on a burger), some diced tomatoes, and a ton of shredded cheddar cheese (like you would put on a coney dog). So, yeah, joke's on us! The fries were thin and crispy, but there was zero salt on them and then you kind of had to eat them with the fork because they got so small and nubby towards the bottom. As for the burger, well, we hate to say this but it just wasn't that good. Very bland. We did love the onion component but the bun became pure mush quickly. Honestly, our daughter's plain cheeseburger was better :( We got a couple milkshakes to go, and while we love a thick milkshake, we do also like to have a proper straw for it! So we sat there and had them with spoons. The chocolate one tastes exactly like a Wendy's frosty and the coffee oreo one tasted entirely like oreo (that were pulverized into the shake). Both were pretty good. Bottom line: we're glad we came, but we do not feel a need to be back. read more

What can I say? Classic diner in historic El Reno. Just off Route 66, Sid's has earned notoriety from its appearances on many food shows like Man v Food and is featured in George Motz's book Hamburger America. The famous Oklahoma fried onion burger was created in El Reno during the Depression as a need to extend the amount of meat that was expensive and hard to come by. Sid's was not the original fried onion burger but it sure is a great one. Crispy flavorful edges and juicy center. Soft melt in your mouth buns. The service is super Oklahoma friendly. We like sitting at the counter for what the husband calls "a dinner and a show." Fun to watch them assemble the burgers. Sid's is a definite stop if you're looking for a great All American burger. But they also have breakfast items, sandwiches, coneys, and malts. read more

The Food is Great, the service was perfect, the owner is super nice so is the staff, we really enjoyed our visit, I highly recommend

As a newbie to Onion Burgers I was overwhelmed with the amount of onions on the burger. Nonetheless, the burger was prepared very well with grilled bun. I'll order a traditional burger next time. read more

For as long as I've lived in Oklahoma City and as many onion burgers as I've tried, I had never made it to Sid's Diner in El Reno. I had to make an unexpected trip to near Hinton, so I decided to stop for a burger on the way home. First off, I loved the place the minute I walked it. It's pretty small and I wanted to watch them make the burgers, so I grabbed a seat at the counter. You cannot beat the smell of onions on the grill while listening to Marty Robbins sing "El Paso" on the radio. And everyone is so nice. I think every one of their employees stopped by to chat or ask me if I needed anything. I miss that. I ordered the regular, a quarter-pound onion burger with cheese and pickles. I'm sorry, but lettuce, tomato or anything besides mustard just doesn't belong on an onion burger. The King - with two patties - is only $6 (!!!), but after a late lunch there's no way I could have eaten it all. When the meat goes on the grill, it just looks like a small puck. They pile a huge amount of onions on each one, then smash them into the burger. This is so much better than simply putting grilled onions on top of a burger. They flip and smash it again to really incorporate the onions into the patty. The patty is reasonably thin, but the perfect size for their buns. It's the equal of any onion burger I've had. I'm a huge Nic's Grill fanboy, but I don't know that I could say which I like better. As John Wayne said in Rio Bravo, "It'd be pretty close. I'd hate to have to live on the difference." The fries were good too, but the burger overshadows everything else. This definitely will not be my last trip to Sid's. read more

Sid's is the home of the smashed onion burger and it was tasty! The service was great and very friendly. The location is very small, as I counted a small number of tables inside but they do have a long counter you can sit at and watch them make these burgers fresh to order! There's also outside (air conditioned!!!) enclosed seating as well as some outdoor tables. Very cute spot. Definitely check it out if you're in El Reno! read more

I don't care for steamed or cooked onions. Having said that, I didn't know this was their thing and so I unintentionally ordered the onion burger. I ordered it the way I normally do, with onions, thinking they would be raw. When she gave me the burger she could tell I didn't know that's how they did it and said she'd make me a new one but first I had to try their specialty. I tried it as she looked on with smug satisfaction, sure she was about to have another convert. I thanked her but said I'd still prefer it with raw onions. She was sad. Having said that, the burger was very good, as were the fries. They have an extensive breakfast menu as well so I may have to check in again before I leave town tomorrow.I can see why they were on Man Vs Food. read more

We were headed back home to Dallas after a weekend in OKC and I convinced my wife to make a 25 minute detour to El Reno. Man, so glad I did. When you pull up to this joint. When you walk in. You instantly feel the history of this place. It's small and quaint and the smell of sizzling burger and charring onions is embedded into the drywall of this place. We were fortunate enough to be seated by the counter so we can get a look at all the action. Let me tell you something, when it comes to piling on the thinly sliced onions, these guys do not mess around!!! Heaps and heaps I tell you. Adam, Sids Diner legacy, even let me creep behind the counter and film him cooking. They even use a special brick mason hardware tool to smash the burgers with the onions on the flat top. Clearly they're serious about smashing the crap out of these things. Looked like a pancake by the time he was done with them. Time to eat. The fries: divine! My burger was straight bliss. Like I never want a burger done any other way again. Just melty cheesy burnt onion meaty goodness! I'm not saying this burger is better than some A5 Wagyu burger you would get for $500 bucks in Michelin star rated New York restaurant. But I'm not saying it isn't either :) Come and enjoy!o read more

Sid's Diner - Diners Near Me - El Reno, Oklahoma

We just had a very bad (I was going to say horrible) experience at Sid's this evening. We sat down at 6:40 p.m. ordered and drink and our food. The drink was delivered quickly, while we began waiting for the food. Other customers came into the diner, were seated, got their food, while we continued to wait. Our waitress never came by to check on us or tell us what the delay was - we had to wave her over. Then she went back to the grill area and did what seemed to be a rewrite of our order. It had now been 25 minutes and we began to think the food was going to messed up anyway so how much longer should we wait. We chose 5 more minutes and still nothing so we decided to leave for a total of 30 minutes in a place where we saw others sit, order, and within minutes their food was delivered. On the way out, I asked to see the manager who was busy at the grill. An older woman in charge was who came to talk to me and she stated she would take care of us if we would sit back down. She also told me she was face down in the grill busy. I had no confidence is how much longer it would take for that to happen or was concerned if they would even be able to get our order right. When I told her just write a note and we will think about coming back to get comped for such bad service and she would not agree to that. Sid's is 12 miles from our home so we really wanted it in order to make that drive. And you have now lost us as customers. We ended getting a really good meal at Swadley's even though they were not our first choice. If you are monitoring these less that complimentary posts get in the diner and find out what's going on. They weren't even busy when we first sat down and still could no deliver on our order. P.S. I woke up today thinking how in the world in such a small space you can look around the dining room and see there's a table with two people at it that are not eating and recognizing you have delivered food to tables around them that were occupied after the ones not eating. Can't you think "there's something wrong!" read more

Awesome folks, food, atmosphere, and history. A must stop while visiting El Reno, Oklahoma.

Such a phenomenal experience! Not only was the burger one of, if not the best I've ever had, my waitress absolutely saved my bacon. Without realizing, I left my company credit card at the restaurant before leaving town and did not realize before I was several states away. Fortunately, Sid's fantastic staff mailed me my card and my employer was none the wiser that I had irresponsibly lost possession! Thank you much! read more

Good food and good service. Get the omelet with hashbrowns and toast. You will walk out full.

I can't believe Yelp is asking for an unbiased opinion of the iconic and Oklahoma staple, Sid's Diner. Basically, I went to Redlands C.C. in 1996. Sid's amongst other similar locations have not changed one bit. Great service and elbow-to-elbow seating, less CVD-19. First time in a lifetime I was up early enough for breakfast in El Reno. Don't get me wrong, my wife and Marine son have a sweet tooth. I knew exactly why I led them there after applying for RealID in Hinton. My wife ordered the French Toast. She said it was the best she had since she was a child. Fluffing rich on the inside with a beautiful light crisp outer crust with proverbial sweetness. My son (who could eat a hog for breakfast had their world-class pancakes. He had no idea pancakes were served that big on such budget-oriented breakfast. He anxiously looked around to ensure he was not in a breakfast eati.g challenge of sorts. Considering we were in the brunch timeline, I opted for the double meat/cheese onion burger. It was a throwback.....way into time, I can't believe I used to eat that with full fries and a Chocolate shake. I was in heaven. Also, we were on the brink of ending the breakfast timeline. However, service here cannot go unmentioned. Thank you Team Sid's. read more

The reason I give Sids diner a five star review is for three reasons, I will start with Sid's being a clean and organized restaurant. The second reason was for the service. It was way better than most restaurants here in Oklahoma. It showed that the staff worked well together and they did a great job. The last reason and definitely not the least important is the quality and the flavor of the cooking. Not sure if the cook was the owner but he definitely had a passion for cooking a good burger. I recommend SIDS diner if you want a great burger. I wish I'd come here soon. read more

Was in OKC area. For 20 years we've always made time for stop at Little Mikes Hamburgers. Incredible onion burgers and onion rings. Friends keep telling us to go west to El Reno and hit Sids Diner. Guy Fieri says it's great. Okay we go. What a mistake. Very little and greasy. Burgers cooked in front of you. Kept watching thinking those are perfect flip them. They don't. Ours all went from brown to burnt black. Said something when served. Snarky girl said that's how they do them. Fries soso. Ketchup was excellent. Don't be a hipster. I'm not. But was talked into it this time. Way overpriced for nasty food. Locals at gas station heard us complaining afterwards. Said next time go to Roberts around the corner. Said that's where locals all eat. Sure will next time. Sids is tourist trap. I never was a fan of Guy Fieri but wife was. WAS. LOL read more
