Check out the local bar scene at Hennessey's - an Irish local pub; choose a dance floor at Jimmy's or grab a cocktail at the Office or the Palm Grill. There are quite a few colleges in the area so there are always people out.
Quick Tips:
Shopping at the Short Hills Mall (15 minute car ride)is a day event with stores like Saks Fifth Avenue, Nieman Marcus, Versace, JCrew, Ann Taylor, Abercrombie & Fitch and traditional department stores. Have lunch at Joe's Bar & Grill or at Papparazzi. Best Way To Get Around:
Walking is your best bet, although for day trips to Philadelphia or New York, the train is your best bet. There is a direct train to the city that takes you to Penn Station in about an hour.
