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.
McDonald’s Angus Burger , only burger they sold for several years that didn’t taste like cardboard.
It was also the only time I can recall them having a swiss and mushroom burger on the menu. It was delicious.
