Now: Similar to Geary Boulevard, Van Ness Avenue is a traffic thoroughfare where larger stores, car dealerships, and chain restaurants find a home. Some highlights of the street include the Opera Plaza center and theatres, and a few unique restaurants. The Cathedral Hill area is named for the cross-shaped St. Mary's Cathedral and Geary and Gough.
Then: The homes that originally existed on Van Ness Avenue were sacrificed to create a line to hold back the fires that followed the 1906 earthquake, and protect the residences to the west.
How To Get There: Van Ness Avenue probably isn't a street that you would want to stroll the length of on foot - there isn't enough going on for that to be fun. Some of the various spots (like Opera Plaza) can be reached by jogging over from Polk Street, or parking on one of the streets separating Franklin and Van Ness.
