Nob Hill
Once home to the mansions of the Big Four railroad barons, Nob Hill retains a sense of wealth and privilege. Some of the city's swankiest hotels are here, as are the ornate, Gothic-style Grace Cathedral and charming Huntington Park. Steep streets are dotted with restaurants and nightspots like the Top of the Mark lounge, with its 360-degree views. The Cable Car Museum exhibits antique cars alongside live machinery.
