The churro 'rueda' (a big coil, for 4 or 5 people) is their best seller (Guía Repsol); there is also a half rueda and a standard portion. Thin, crisp churros with thick chocolate, the 'bucket of churros with chocolate' to share and freshly squeezed orange juice. If you are looking for porras, they are called tejeringos here.
Marbella's first churrería: Ramón Navas opened it in 1941 and his son Pepe made it famous. It has a big terrace right on Plaza de los Naranjos, the heart of the old town.
Go early, when the square is still quiet: in summer they serve thousands of people in a day (Guía Repsol). The terraces on Plaza de los Naranjos tend to be pricier than those on the back streets. Cards accepted and dogs allowed.
The old town is pedestrianised: leave your car in a car park in the centre and walk up to the square.
