About Us

Welcome to Sid's Diner in El Reno Oklahoma. Our small diner offers a homey atmosphere and serves El Reno famous fried onion burgers also known as The depression burger. Back then meat was expensive and onions were cheap so in order to make a hearty meal onions would be used as substitution. We hand roll our patties every day and smash thin sliced onions on top. All the mean while everything is cooked fresh right in front of you. It's an experince that's rarely around anymore, you'll surely enjoy the 50s style atmosphere.


Sid's Diner will close at 2pm on Friday December 24th and reopen at 7am Monday December 27th for Christmas. Sorry for any innconvinience. Merry Christmas and happy holidays.
