Not that it fits the title because everyone has heard of it, but I nominate another.
The Torta Cubana. Fitting in well with the theme of monster sandwiches, this beast has all the meats (ham, chorizo, hot dog, and a bun filling breaded beef cutlet) and oaxaca cheese, then lettuce, tomato, onion, and avocado, topped off with some mayo. Makes for a belly busting meal.
I get one at:
