Western Jerusalem is the area to the south and west of the Old City, including the lively downtown shopping and nightlife area of the Ben Yehuda Street pedestrian mall and neighboring Nahlat Shiva district, where you'll find great boutiques, cafes and bars.
Lots of neighborhoods worth exploring in western Jerusalem--Nachlaot, near the Machane Yehuda Market, where plaques and photos dotted around the area tell the story of the families who founded the neighborhood.
Stroll through the King David Street area, home to the YMCA and its observation tower; the luxurious lobby of the King David Hotel and Yemin Moshe, the first neighborhood to be built outside the walls of the Old City.
Wander off King George Street to the pedestrians-only Schatz Street and Bezalel Street mall, filled with fashion boutiques, bookstores and cafes and a Friday crafts fair between April-November.
Don't forget Jerusalem's Cultural Mile in and around Talbieh, that is home to the Liberty Bell Garden, the President's Residence, the Museum for Islamic Art, the Jerusalem Theater, the Menachem Begin Heritage Center and the Jerusalem Cinematheque.
