ABOUT MADRID FOOD
Overview: Spanish food is somewhat bland. Sorry to be so abrupt. Spanish people do not like spicy food. Spanish food and Mexican food, are not the same, by the way. We're talking about European food versus Mexican food. The Spanish are into cold cuts and meats, especially dried pork and salami with bread.
One thing I really enjoyed and liked about restaurants or cafes in Madrid are the numerous restaurants for quick jaunts: you stand at a counter, order quickly, eat and drink standing up and then take off. The counters are somewhat high but there are random, small tables for the occasional customer who likes to sit and take a little longer to digest. Of course, I didn't see many of these quick cafes in the Salamanca or Cuzco areas. Be that it may, grab a quick café con leche with a borro or churo and dash off.
Madrid also has lots of pastry shops and...they are GOOD! Find them on Calle de Alcala en route to Atocha Railway Station as well as in the Salamanca area.
In Madrid, there's a restaurant or cafe or standup joint in virtually every other building.
