hamburger

The simple hamburger has come a long way from being topped solely with lettuce, tomato and onions.

Indeed, many New Yorker's go to great lengths to replicate Shake Shack's addictive "shack sauce" to top their burgers.

While west coasters know to order their In-N-Out Burger's "Animal Style" to get the added grilled onions, thousand island sauce and extra pickles on a mustard grilled bun.

But these are relatively simple compared to many other variations on the simple, All-American hamburgers, as everything from a blue cheese, barbecue burger to a Kung-Pow shrimp burger can be found on menus all over the world.

And while some of these seemingly questionable experimentations proved to pay off handsomely, others most definitely did not.

Making pineapple on pizza seem positively tame.
