Back in the disco days, I used to burn off a thousand calories or so on the dance floor at a local restaurant called O'Callahans -- and then put back probably twice that many by ordering their "Garbage Grinder" burger.

IIRC, it had 1/4 lb. (at least) hamburger, cheese, bun, a fried egg, 2 strips of bacon, mayonnaise (I might have had them hold that), ketchup (which I definitely did have them hold), mustard, pickles, onions, tomato, lettuce. It might even have had guacamole too.

But that was real "comfort food!"
