"Why don't they just throw a side of beef on a bun with all the fixins'and serve it."
Your post just brought back a very vivid recollection. As good as this burger looks there is one that goes it one better.
Fuddrucker's has one of these- all the cheese and bacon- mayo and a full pound of beef!
I had one of those suckers in February of this year and within just a couple of days I underwent emergency bypass surgery. Serious- no joke!
We just got a Cheeburger franchise here. You can get a 1 lb. cheeseburger with sauteed mushrooms and onions, whatever condiments you like and served with a real milkshake (made with Edy's premium ice cream and whole milk), and an order of 'Frings' (french fries and onion rings).
If you can eat the whole thing, they'll post your picture on the wall.
They should sell a life insurance policy to go with it. :-)
