How to get most out of a visit to San Francisco?

Hey everyone! I'm owner of the small web development company in Europe. At this moment I'm planning my trip to San Francisco (31.OCT-15.NOV). I'd really like to meet with interesting people and to visit great companies to see how you guys are building amazing services and applications! Where to go, whom to meet, how to visit Google :), where to stay for 2 weeks, what kind of events are there? Any type of info is appreciated! And of course I'd be glad to have a cup of coffee or a glass of beer with anyone interested in experience sharing! Just send me a note :) Cheers, Jean Mauris jean@true-vision.net
