Excellent! Shadyside's been needing a good coffee shop, and Adda fits the bill. This place is super inviting, nice tables and intriguing books and stuff, and the baristas (a knowledgeable crew from some of the city's other great places incl. Commonplace) are both skilled and kind. Had a delicious Verve-roasted Ethiopian espresso, and they do Chemex as well which I'll try next time I'm there. They do have wifi and ~8 tables, so I'd try working there too; not sure if it will start to fill up.
