Looking for a venue in Silicon Valley (probably not as far down as San Jose) for about 30 C-suite executives. Can be a restaurant (buyout or private room), cultural institution, winery, etc. Open to any high-end ideas. Thanks!

Looking for recommendations for the BEST hotels in the US (high end luxury, incredible service, more modern in style, easy to get to!) for a group of about 40 to book rooms and meeting space! I have Rosewood Sand Hill and Andaz Scottsdale on my list so far
