A picture taken of downtown San Francisco at Union Square. Union Square is one of San Francisco's commerce and cultural centers. The 245 foot long granite central plaza invites street performers to its four corners and has plenty of space for staged events, art exhibitions, and concerts. The area around Union Square -- Post, Stockton, Geary, Powell, and Sutter streets, are a tribute to the power of shopping. Every major department store is within easy walking distance of the square. Views of the Union Square area are best from Harry Denton's Starlight Room in the Sir Francis Drake Hotel and from some of the second and third floor galleries and shops surrounding the square.
