Go bunless! Enjoy a ShackBurger®, Hamburger or Cheeseburger (single, double or triple) sans the bun. This option goes for all our burgers except the 'Shroom Burger, which has breadcrumbs in it.
Try any of our dogs – just lose the bun. Drag 'em through the garden too, if you're looking for an even fuller flavor!
The fries are gluten-free, but if you have severe reactions to trace amounts of gluten, it might be best to skip the fries. See, our fryers prepare the 'Shrooms in separate oil, but each night the oils get filtered through the same equipment.
Frozen Custards are a-okay without the cones. But before ordering the custard of the day, double-check the ingredients with our cashier to make sure it's gluten-free. Shakes are okay too, just not malted.
Steer clear of all other toppings and cones.
