Steak 'N Shake still makes their burgers ('Steakburgers') from fresh, unfrozen, ground beef fried on a grill right in plain view.
They're pretty good too.
As long as you don’t mind a burger floating in its own grease when its served to you.. Of course, for $3 or $4 bucks you are going to get a very high fat ground beef.
I’ve been very happy since In N Out came here to Texas.
