Coffee Shops

I not only love coffee, but when I am in school or studying I feel as though I need coffee. I think that they call this an addiction. I live on Capitol Hill and there are a plethora of coffee shops and for the most part they are pretty similar. too cool baristas that probably have Phd's in philosophy (maybe that's why they look so unhappy), fine crafted and roasted coffee, they're expensive, all drinks have double shots...the list goes on. So what narrows it down for me is taste, attitudes of the people who work there, convenience, and atmosphere.
