The Best Onion Burgers in Oklahoma City and El Reno | Eater
"A famous diner known for its thin, smash-style onion burgers loaded with onions that range from grilled to slightly burnt; burgers are typically dressed with mustard and pickles (unless requested otherwise) and come with crispy hand-cut fries, the assertive char on the patty balancing the sweet, buttery onions and tangy mustard." - Amy McCarthy
