Shake Shack Introduces a New fancy Black Truffle Burger

YUMMMM OMG Shake Shack just upped the game with a brand new Truffle Burger! They teamed up with a specialty importer named Regalis Foods that works with Michelin-starred restaurants to offer a limited edition burger with a black truffle sauce, real truffles, caramelized mushrooms and aged sherry vinegar. They will also offer a black truffle Shroom Burger for those that don't eat meat. If there just doesn't seem to be enough truffle for you...have no fear...you can order a side of the black truffle sauce (great for dipping fries) for an extra $1.50
