My addiction appreciation for coffee was spurred by The Dutch boyfriend.  He romanced me with making me a kickass cuppa every morning.  It was love at first expert microfoam.  The rest is history.

All romanticism aside, I love the perfect cappuccino made with geekiness and obsessiveness of a Type A barista.  And of artisanally roasted beans (I prefer it on the dark side), fair trade and organic, when possible.  It realize it is utter snobbery, but if you've had a rich coffee, you know you can't go back to Starbucks ever.  

But more than the coffee, I seek out cafes wherever I travel as a way to feel the pulse of a place, in the hopes of getting initiated into the local culture, and to belong to that local scene, albeit temporarily.  Besides, cafes photograph well!
