Built in 1926 on the spot where railroad millionaire Mark Hopkins’s turreted mansion once stood, the 19-story Mark Hopkins gained global fame during World War II when it was de rigueur for Pacific-bound servicemen to toast their goodbye to the States in the Top of the Mark cocktail lounge. Nowadays, this grand hotel caters mostly to convention-bound corporate executives, since its prices often require corporate charge accounts. Each neoclassical room is exceedingly comfortable and comes with all the fancy amenities you’d expect from a world-class hotel, including custom furniture, plush fabrics, sumptuous bathrooms, Frette bathrobes, and extraordinary views of the city. The luxury suites are twice the size of most San Francisco apartments and cost close to a month’s rent per night. The Top of the Mark, a fantastic bar/lounge (open daily), offers dancing to live jazz or swing, Sunday brunch, and cocktails in swank, old-fashioned style. (Romantics, this place is for you, but keep in mind that there’s a $10 cover fee Wed–Sat after 8:30pm for the live nightly entertainment, and $5 on Tuesday.) The Nob Hill Restaurant offers California cuisine nightly and breakfast on Sunday.
