Now: A blinding swirl of singles bars, eateries, boutiques, spas, Union Street is one place where wealthy young people come to play, and sit in front of tablecloths beside longtime Marina residents. The sound of this area's nighttime merriment is distinctly (Cow) Hollow.
Then: Named for the area's incarnation in the 1800s as a pasture for grazing cattle. The Octagon House was built in 1861, and designed to let sunlight into every room.
How To Get There: The 22 Muni bus crosses Union Street near the end of its long trip down Fillmore Street. If you're already in the Marina, it is easy to jog over from Chestnut Street at Fillmore. You can also turn on to Union Street from Van Ness Avenue, and then try to park right away before the beginning of the commercial area at Gough Street.
