Drip sources its coffee from the legendary Underdog roastery in Athens, and it's fantastic, served in a minimalist yet rather relaxed atmosphere in a location a bit off the beaten track, but more than worth the trip. (You will find it just south of Piata Unirii). There is tea from Paper and Tea in Berlin, and croissants and cakes made right here. You can buy the coffee to take home and prepare yourself too.
