Rodilla has to be one of my favourite “Fast Food” restaurants in Madrid. It offers a huge range of sandwiches, from foie gras to prawns. My favourite sandwich just has to be ‘ensaladilla’ – which have tuna, mayonnaise, peas and artichoke. Their sandwich bars can be found all over Madrid, including Puerta del Sol, Plaza de Callao, the Goya area and Argüelles. They also do nice salad bowls, too.
