This is definitely something to keep in mind for this coming weekend. During the 25, 26 and 27th of April there will be a special tapas route in the Calle Feria area (comprising Feria, San Luís, Relator, and Correduría streets). More than 20 bars and restaurants will be participating with each one offering a special tapa for you to try with either a beer or soft drink for just 3€.
