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.
It was actually the steak bagel breakfast sandwich at McDonalds… until that garbage institution actually brought it back defector! It trned out to be a weaker approximatation with different/less seasoning on meat and different sauce, but close enough for nostalgia
