Free refills on coffee. Now that's sweet. I dig Caribou Coffee, I dig its cozy feel and the friendly staff. I'm digging sitting next to the window and watching all the Forbes Avenue craziness when I should be writing.
The only problem is that during the college school year this place often gets so packed you can't find a seat. But you'll have that when all the students are in Oakland. If you find a seat you will enjoy yourself, but good luck finding one Monday through Thursday during the afternoon. That seems to be study time at PITT.
