The impressive California Street Center is located within a stunning high-rise building with a well-lit lobby in the heart of San Francisco's financial district. The city is a world banking and finance hotspot, helping to give it a GDP bigger than that of some countries. There are many professional services to support the financial sector, but the proximity of Silicon Valley means there's plenty of high technology activity too. Around 80 per cent of businesses have fewer than 10 employees and the city continues to be popular with entrepreneurs establishing start-up companies. Tourism is vital to the city's economy and many of the top attractions are nearby. The historic waterfront along The Embarcadero offers restaurants and shops, and the famous California Street Cable Car Turnaround is a short walk away.
