I’m with you.
I rarely purchase burgers from the fast food guys.
Then you would like the Greek diners in my area that make burgers. There is a legendary one off the 405 fwy and Cherry Ave. Long Beach, CA.... my Dad use to go there for chili burgers when he drove in from LAX home from work. He took me by that one years ago... all I can remember is the portion was so huge, no way one person could eat it all.
