Tapas bars in Madrid

Spaniards love their own schedules.  Most establishments close between 2pm to 5pm for siestas.  Restaurants don't open until 10 at night.  But Tapas Bars offer happy hours before then.  Wine and beers are the choice drinks.  Tapas are at times free.  Those ones are old recycled food sprinkled with lots of salt to make the customer thirsty for more drinks.  Ole!
