Pork belly sandwiched in two hand-ground patties

Just launched at Bluestem Brasserie and only sold on Fridays (sorry, 2010 Kirstie Alley), this 13oz burger to end all burgers features two patties of ground brisket and sirloin, plus a slab of crispy pork belly (!), plus plus caramelized onions, a sunny-side up egg, and aged cheddar, plus plus plus a side of Kennebec truffle fries.
