My two friends were management consultants -- which says it all, really

The Privium guide to top cities of the world has this to say about Madrid:

Unless you want to be written of as a cultural barbarian when you get home, you shouldn't miss highlights like the Museo del Prado ... Don't try to do the Prado in one day though, just limit yourself to remarkable works like the portraits by El Greco or Goya's bloody battle scenes.

The last time I visited the Prado was in 1997, along with two friends from Oxford. We managed 5 minutes before deciding it was time to check out the cafe. And then some tapas bars. We never made it to the Goyas or El Grecos. Cultural barbarians indeed.
