4. Big Kahuna: Kenny's Burger Joint
This burger's so monstrous, it barely fits on the bun. And it doesn't fit on the menu at all. That's because this secret burger is only available to those in-the-know, of which you are now included. Two patties, pepper jack, secret sauce, pickles, LTO, mushrooms and bacon. And that great wood-grilled taste.
