"The Veggie Shack, doesn’t try to disguise its contents as anything other than good ol’ fashioned vegetables. The burger is filled with mushrooms, sweet potatoes, carrots, farro, and quinoa. It was flavorful and juicy, and full of discrete chunks of the aforementioned veggies, rather than an all-too-common mash of them. The patty was sandwiched between Shack Shack’s signature pillowy potato roll and slathered with Shack Sauce. The burger was stacked with American cheese, pickle medallions, and crispy fried onions." - ByLi Goldstein
