The holy trinity: Upper, Midtown and Lower East side. Something for everybody. The upper is posher than posh. Serena and Blaire's playground. The richest of the rich chill out here. Midtown is skyscraper country with the Chrysler Building and Rockefeller Center as eye-catchers. Lively, 24/7 and always go, go, go! Lower yourself. Lower is trendy, with a mix of raw and luxurious. Whichever neighborhood you choose, east is best!
