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.
Don’t know whether pizza from a place you can sit down in and eat counts, but there used to be a place called Rocky Rococo’s. Best pizza in the whole city, until they disappeared off the map. Now I’d have to go to the other side of the country just for their pizza. For a place I wouldn’t consider a restaurant, they had some of the absolute best pizza I’ve ever had.
