Sids Diner - El Reno

The best onion burger I've ever eaten. Our first visit today and not the last. We drove from Piedmont and about halfway back I wanted another one. To eat everything, but I wanted another one. Everybody was super nice. Had to wait to come in about 15 minutes, but it's worth it.

Lived in Oklahoma all my life and I'm just now finding out about this hidden gem!!! I got the King and 1/2 order of FF (is all you really need) to have room for the amazing the chocolate peanut butter shake Found themselves another regular all the way from Tuttle, OK!!

I love this place!!! The best coney and peanut butter chocolate shake around

We were cruisin Route 66 and read about Sid's and the Onion Burger. Had to stop, and very glad we did. Great local joint, with true Americana. Great onion burger and fresh fries. I will recommend and will be back if in the area. Service was fantastic too. All waitress's seem to work together.

Best fresh made to order burger I’ve ever eaten! The french fries were hot and delicious! Great atmosphere.
