One of the early movers in Lisbon's fledgling burger scene, Ground Burger arrived in 2015 and has since cemented itself as a cult favourite. The brand has two locations: Time Out Market, and near the Gulbenkian museum. They offer a true experience, so try their burgers of the month, or indulge in a lobster one paired with a sour from one of Lisbon's largest craft beer collections. The burgers are not the only thing to write home about. Their fries, subtly tossed in garlic and rosemary, are a delight.
