Sid's Diner in El Reno is a nostalgic-style diner serving breakfast, lunch and dinner. This decades-old Route 66 establishment is famous for El Reno-style fried onion burgers, cooked to order. At Sid's, you can expect a hand-formed patty combined with a heap of freshly shredded onions married on a seasoned flat-top grill for an experience that's caught nationwide acclaim. Pair your Sid's burger with an old-fashioned malt or shake made with real ice cream and a variety of flavorings including peanut butter and classics like vanilla. Order a coney covered with chili sauce and Sid's trademark slaw and enjoy your meal surrounded by a healthy dose of small-town charm. Whichever entree you choose, don't forget to add a side or two of Sid's freshly cut fries or thick, golden onion rings.
