The Cervecería Santa Bárbara in Madrid´s Plaza Santa Bárbara is one of Madrid´s more famous drinking establishments. The main beer on tap is a local lager called Mahou, you can also get a dark beer and alcohol-free lager from the same company. The bar was established in 1947 and is well-known for the huge range of shellfish and other fish which it sells. You won´t get tapas in this bar but can buy its delicious shellfish from a separate bar – cockles, prawns (shrimps), mussels and my favourite boquerones (white bait in vinegar).
