The operative word for this scenic corner of San Francisco is "fun." Besides excellent shopping and dining, there are three palace-style movie houses, live theater, museums, and miles of gorgeous paths and trails inside the Presidio and along the Marina Green. If you live here, you can wake up on a sunny Sunday, take in a latte with your paper on Chestnut Street, stroll to the Palace of Fine Arts, rollerblade on the Marina Green, and finish with dinner and a movie on Union Street. The Marina and Cow Hollow are separated by Lombard Street, a busy six-lane thoroughfare that whisks Marin Commuters towards downtown. Below Lombard in the more crowded Marina neighborhood, are 1920s "Marina-style" homes and apartments with practical layouts and lovely features like high-coved ceilings and bay windows. Above Lombard Street in Cow Hollow, you'll find older architecture with quaint cottages, dramatic mansions, and turn-of-the-century apartment buildings.
