For those who thrive in happy paradoxes, Jump’n Java is the ideal cafe. The space is cozy yet feels spacious, with large, light-welcoming windows. Small tables allow for anonymity, though at the same time, visitors must share a convivial seat on benches running the full-length of the walls. A tropical-island mural makes for a kind of vacation experience, even while most patrons settle in with free wi-fi and very good coffee for serious work. Nourishment in this oasis of contradiction includes empanadas, piroshkies, spinach feta pie, and Zoe’s sweet treats.
