"As for my onion burger, I drove several hundred miles out of the way to El Reno, Oklahoma on a trip from Los Angeles to Dallas just to try one. On my next trip to Dallas, Sid’s will be a destination stop no matter how out of the way it is. My burger was cooked perfectly, not greasy, and the onions took it over the top."

Lonely Planet

"The most heralded of El Reno's onion burgers with lines out the door to prove it. Sit at the counter to watch the burger-making magic or relax at a shady picnic table outside."

Thrillist

"This bright red beacon and its old-school American burgers and breakfasts call out to everyone, even the dude from 'Man V. Food.' Inside, locals and tourists who stop by just for this food fork over their cash at the simple little counter, which slings out a burger that's solidified El Reno as a destination for anyone and everyone passing through OKC. Most notably, it's the cheesy onion burger without mountains of pickles that did it."

"A few months ago I visited with my wife and kids again. It was just as good as I remembered. At Sid’s, the meat is placed on the grill in a ball and then pressed down into a flat patty. The resulting burger is nicely charred on one side with caramelized onion on the other. If you are ever in El Reno Oklahoma, Sid’s Diner is a place you’ve got to try."
