I just came across this photo I took last summer in Tokyo, which I clearly forgot to post at the time. What a ridiculously awesome sandwich. I'm pretty sure the Japanese on the poster says, "An honorable way to die. Get one today!"
Three all beef patties, special sauce, lettuce, cheese, pickles, onions, bacon, and an egg on a sesame seed bun... (The song and the sandwich are clearly better with the egg, bacon, and extra patty.)
