From the Gold Rush through the Summer of Love and to the more recent evolution of Silicon Valley, San Francisco has always been known as a hip breeding ground for new concepts. If it's exceptional, fun and forward-thinking, it probably belongs in this city by the bay. This bohemian and urban utopia is home to some of the coolest spaces on the planet--with an abundance of tourist, dining, shopping, and leisure options--bar none. Whether it's the stylishness of Top of the Mark, the restrained simplicity of the de Young Museum, or the original chic of gathering spots such as Absinthe and Gitane, this stunning city truly does have it all.
