The tourist trail leads directly to this door, and there are the photographs of visiting celebrities to prove it – Christopher Lee, Paloma Picasso and Maradona among them. Its cool white marble interior feels opulent, while efficient, slightly world-weary, staff guide visitors through the process of ordering chocolate con churros – a fried-dough pastry served with thick hot chocolate, almost pudding-like in consistency and less sweet than one might think, to dip them into. A single order of six churros and a cup of chocolate between two should suffice for breakfast or a very late bite after a night of revels.
