Lonely Planet Publications Pty Ltd has their San Francisco City Guide (iTunes Link) in the iTunes App Store for FREE (regularly $5.99) for a limited time.

Let other cities build grand monuments. San Francisco days are better spent sunning by the bay and digesting lavish seafood dinners – no matter whether you’re a human or a sea lion that’s bellyflopped on Pier 39. Outlandish behaviour comes with the territory here. What with all the earthquakes and eccentrics, this peninsula keeps only a tentative hold on the planet, not to mention the continental US. But as any San Franciscan will tell you, gravity is overrated, anyway.
