Deep in Salamanca's Mercado de la Paz, Casa Dani is a wildly popular spot for lunch and it gets going earlier than most: most weekdays, there's a queue at 1pm. But any time is good for the homemade tortilla de patatas (potato-and-onion omelette), which is among Madrid's best. Pull up a bar stool if you don't fancy waiting for a table.
