Don't go home after HubBub. Take your coffee and explore the fun side of Philly's financial district.
Study: The Free Library of Philadelphia, 4 blocks away (1901 Vine Street). Put your caffeine buzz to good use: ditch the depths of VP for the spacious halls of the Free Library and catch up on your work (it has free WiFi!). You might even stumble upon a reading by a famous author or an impromptu film screening.
Eat: Love Park, 3 blocks away (Broad Street and JFK Boulevard). Take a study break and show mobile vendors some more love.
