Bun is a fast food restaurant where good food, design and quality come together to create a revolutionary experience. Bun offers a type of burger from the United States, the smashed burger, characterised by a cooking technique that consists of smashing the meat patty on the griddle. The result is a tasty burger, crispy on the outside and juicy on the inside. One of Bun's core values is inclusiveness, and this is also reflected in the menu, which is entirely plant-based with Beyond Meat burgers. It is defined as “meat-not-meat” and is a protein-derived, fully plant-based product with a taste and texture virtually superimposable on the animal-derived alternative. Bun is the first fast food restaurant in Italy to offer an entire menu that can be converted to a vegetarian version. Bun's product offering also includes innovative alternatives, such as the protein burger, which instead of bread has a salad leaf around it, and the dog lovers, a menu designed for four-legged friends.
