Buenos Aires is hands down one of my favorite cities in the world. The eclectic mix of architecture, culture and history is enough to keep one happy for a lifetime. But as with all great cities, after dark (especially in Buenos Aires) is when you get to see yet another side of an already multifaceted land. Simply walking the huge arcades as the sun goes down, with your same-but-now-different surroundings twinkling and glowing around you, will fill you with awe and wonder, and you just may want to keep on walking and walking and walking . . .
