Hamburger bread, crudely cut(wasn't even cut to the end), buttered and grilled. Tender, juicy beef patty. Cheese. Shake sauce( loved it! Tasted like mustard + something). Mushroom patty, one single huge portobello mushroom. Tomatoes. Lettuce. Tasted like heaven. Must try in NYC! Don't be scared off by the queue, it moved really fast!
