A long day of meetings is not so bad when your Spanish colleagues take you out afterwards for drinks on the rooftops . . . 

. . . followed by an incredible dinner of sautéed mushrooms, heirloom tomatoes, steak, and melted cheese (all for only 20 euros!) at an old-school madrileno bar.

I may however regret staying out till 1am when the alarm goes off in the morning.
