Johnny Rockets has a vegan Gardein Black Bean Burger on their menu. The fries, tots, and applesauce are vegan.
For a temporary time, at select locations, you can find the Impossible Burger, Daiya Cheese, and Craig’s vegan shakes. Menu varies even within the Puget Sound area.
Be aware that vegan products are cooked on the same surfaces and fryers as non-vegan items.
