Here, for a while at McDonald’s there was a 🍔 called “the 1955” and it was the best, big pieces of onion, an special sauce, buns and big piece of beef with bacon (for Europe standards anyways) it disappeared once and came back for an encore only to be removed again and never return.
The sourdough ranch bacon cheeseburger from Carl’s Jr was my go to burger back in the early 2000s. They brought back another sourdough sandwich a few years ago and it was also good but unfortunately that’s also discontinued.
The sourdough from Jack in the Box is close but with the lack of lettuce and onions feels a little dry.
