My favorite coffeeshop in Squirrel Hill. The staff is friendly and knowledgeable, and they work very hard and efficiently, considering they're usually staffed with one person. Be ready to be patient.
They've got a great selection of coffees--drip, trifecta/clover by the cup, espresso, and lattes with house-made syrups. They've got a pretty big loose-leaf tea selection as well.
Lots of the tables & chairs are wobbly, and the cafe is immediately cold every time the door opens.. but I go there for the coffee.
