Before we get on the plane to Amsterdam, I wanted to give a quick plug for The Edge in Providence.
The Edge serves delicious coffee (the best I've found along the east coast of the US, although I'm admittedly not well-travelled here), as well as tasty sandwiches, wraps and cup cakes. On top of that, they have magazines, free wireless Net access and a few toys for children; and all of that in a relaxed, friendly atmosphere.
In short, if you find yourself in Providence and like excellent coffee, give The Edge a try. I particularly recommend the traditional cappuccino and the Black Cat espresso melange from Intelligentsia.
