New Delhi, Jan. 28 -- Walking from my hotel to the cafe DOP, I braced against the chilly morning air. I was on my way to get my morning cuppa, and a friend who had once lived in the city recommended it. The cafe has more than just caffeine to offer, serving up rustic Italian street food like a mortadella piadina (an Italian flatbread) and ricciarelli (chewy almond cookies). Even in two-degree weather, the walk-up window has regulars waiting for their turn, breath turning to ice as they order.

It's my last day in Canberra, Australia's capital and I managed to have exceptional espressos on a daily basis. Whether at Barrio Coffee Collective in the neighbourhood of Braddon, or Doubleshot in the suburb of Deakin. Great coffee may seem like it...
