"I'm going to London," I said, "... to see the Spice Girls Reunion Tour!" My friend's facial expression changed dramatically as I finished the sentence. "To what?!?" To see the Spice Girls, but obviously, to see London as well. The concert was technically in Wales, but before there were zigs and zags and ahs in Cardiff, there were empanadas, gold leaf lattes (!) and long walks saturated with sights in London.
