Frank Hearts Berlin
With some seriously mouth-watering burgers on their menu, the hype and the long queues are just part of the fun at Neukölln's Berlin Burger International. Their burgers are wide enough to make you question whether or not you'll be able to finish it - with two sesame buns holding everything from the classic beef and cheese to guacamole with sweet potato chips. Accompanied by a beer, delicious potato wedges and vibrant, cheerful staff BBI serves up burgers that are worth the wait.
