Shake Shack keeps its menu simple and focused, which makes choosing lunch easy. The ShackBurger is the classic pick, while the Chicken Shack is a good choice if you want something crisp and lighter, and the 'Shroom Burger gives vegetarians a filling option with a fried portobello mushroom.
Crinkle-cut fries and a hand-spun shake round out the meal nicely, and the burgers generally run about $6-$11 before extras. Prices and calories can vary by location, so it is worth checking the current menu before you order.
