Sid's Diner

The Original Oklahoma smash burger, and best hands down. Adam was amazing, attentive to customers and to me he's the best! His grilling was on point with making burgers. I sat right behind the grill which to me is the best seat in the house because you've got birds eye view of the deliciousness going down. Taste was amazing and this place is legend. I live an hour and a half away and will definitely make that drive for another burger. Environment there is very welcoming and make you feel like you're at home. If you've never been here you need to go!

Sid's Diner - El Reno, Oklahoma: A Route 66 Icon and Home of the Original Onion Burger. Sid's Diner in El Reno truly embodies the classic American diner experience. As the proud home of the original Oklahoma onion burger, this small, bustling spot lives up to its reputation. We visited during the lunch rush, and while the limited seating meant a bit of a wait, it was well worth it. The hospitality here is as incredible as the food. The staff were super friendly, and the owner (a third-generation family member!) took the time to greet us personally and chat about the restaurant's rich history and its deep connections to Route 66. It's clear the passion for this place runs deep. And the food? Simply amazing. We ordered the signature original onion burger—a must-have—and a small order of f

Amazing! These guys know what they're doing. Their food service what an amazing place to eat. Saw them on YouTube and I have to tell you their food tastes better than it looks it's just awesome. Their food looks great.

I loved Sid's. Today was my first time eating there. It was a Wednesday, right at the lunch rush, but the very nice and friendly staff sat us within a few minutes when a couple spaces opened up. We sat at the counter and got to watch Marty the owner work his magic on the grill. We (my father and I) both ordered the single onion burger with cheese. We shared the half order of fries and onion rings. WOW, I have heard about these burgers for awhile now and they do not disappoint. I had sky high expectations and my burger met those. I highly recommend Sid's. I wish I had more room after for a shake but I just couldn't fit another thing in my stomach. 5 stars all around, great food, friendly and happy staff, and even though it is snug in there it feels like an old diner and I love that.

Came into Sid's Diner to have dinner, I was wowed the moment I entered and was greeted as though a member of my family was greeting me. The restaurant is extremely clean and spotless. The decor is amazing and the Diner felt so warm and comfy, it was such a pleasant atmosphere. This Diner reminded me of the Cheer's Pub where everyone knows your name. The other patrons were so friendly and many greeted me as well and the history of Sid's everyone seems to know. Now, for the food, I had the famous onion burger and onion rings to boot, the food was par excellence and yummy. I asked the cook if it was legal to sell such amazing burgers, turns out I was talking to Marty, the owner. Marty said he was retired, from what I saw it didn't look like a retired person to me, Marty was shaking and bak
