I actually ate a Burger King quadruple stacker once, just because... That'd be a quadruple-patty bacon cheeseburger.
I once ate four McD's Quarter Pounder w/ Cheese when they were on sale $2 for 2... just because someone with me said I "couldn't do it". I did "cheat" and left the fake onions off, just 'cause they're nasty. I typically don't do ketchup and very rarely mustard on those, though. Plain chesseburgers are just fine by me.
If I'm making them myself, expect garlic... lots of garlic, some other herbs perhaps on whatever whim of the day is, and plenty of fresh ground black peppercorns mixed into the meat. Since I'm lazy these days, perhaps that stuff will just be sprinkled on a pre-formed frozen "hocky puck" from Costco but it'll still be there. A little cheddar, maybe a quick slice of bacon... all good.
I can make large quantities of food disappear very quickly, virtually on command, but I don't do it regularly.
Best pizza ever was at Garcia's "Home of the Flying Tomato" in Champaign/Urbana, IL just off the UI campus. But that was in the mid-90's and apparently they're gone now, according to this...

Deepest "deep dish" I've ever seen, more like pie than what most people think of as pizza. Even came in one of those aluminum pie tin things. You'd order a "large" and get something that looked like a "small" anywhere else, until you tried to lift it.
They did something to the tomatoes... perhaps even used tomato paste straight from the can?... to make it really sweet, and the stuff truly was better after sitting overnight in the fridge so it could fully solidify into a three pound mass. Then you'd eat it cold or room-temperature. Pure awesomeness.
That photo the guy posted at the end of that where he made his own from memory, isn't even close... it was at least 2" thick, if not more.
Sounds like from that website that they had quite an empire going for a while with up to 18 stores, but the owners sold and down the drain she went... bummer. I always had dreams of going back there someday for another slice... but nothing lasts forever.
