No chain that I know of can make a great burger. I graduated from high school in 1956 and all through my school years burgers were 10¢ and were grilled in the grease along with the bun, mmnn mmnn mnn good.
There is a chain called Fat Burger that makes a pretty good burger, In&Out ehhh, so, so.
When I make burgers at home I like to fry the buns in the burger grease. Awesome good!
