Burger King's Poutine and Large Hash Browns are two popular side options, each offering a unique taste experience. Poutine, a Canadian specialty, features crispy fries topped with cheese curds and gravy, while Large Hash Browns are shredded potatoes, golden-brown and crispy. Poutine is richer and messier due to the gravy and cheese, while Large Hash Browns are simpler and crispier. Both are delicious choices to complement any Burger King meal, catering to different taste preferences.
