Bow Truss has since shut down, but Passion House operates in one old Bow Truss location. I was really not a fan of the coffee I had brought home from Bow Truss, but I liked the atmosphere and friendly staff.
You can't go wrong with Intelligentsia.
Caffe Streets was very tranquil and the coffee they serve (Metric) was very tasty.
Dark Matter; Osmium, Ipsento, La Colombe, Gaslight, and The Wormhole were 5 that my wife and I did not have a chance to visit, but I have only heard good things. I hope that you enjoy your trip and that it is well caffeinated!
