As far as the "most exclusive" areas, while others have indicated general neighborhoods, I would need to show you specific pockets and levels of exclusivity in each area.

If you want to travel a bit south there is also Monte Sereno, which neighbors Los Gatos. Or even a bit further south to Pebble Beach, and Carmel Highlands.
You are right. West Menlo is expensive but price usually tops out at $4M to $5M. Given the $10M specified in question, I choose not to include MP. Don't know that a Menlo Park house has ever sold for $10M.
Since the "Bay Area" encompasses a lot of territory you have a lot to choose from:
In the city of San Francisco the highest priced Real Estate will be found in Pacific Heights, Presidio Heights, Russian Hill, Marina, Cow Hollow, North Beach, Telegraph Hill, & Seacliff area.
In the areas of Marin County that are reasonably close to the city Mill Valley, Tiburon, & Belvedere.
On the Peninsula your highest dollar areas will be Hillsborough, Atherton, Menlo Park, Los Altos Hills, Palo Alto & Woodside.
If you want warmer weather there are several communities in the east bay, Piedmont being the closest.
If you are really serious about buying in this price range, here are a few things you should consider to help define which of these areas will be most interesting to you.
Proximity to San Francisco
Weather - we have lots of microclimates, in San Francisco a block or two can make a huge difference.
Walkability to shops/restaurants
We work in all these areas and would be happy to send you a breakdown on what's available as well as highlight the differences between the areas you choose.

San Francisco's North Side is comprised of some of the best Real Estate in the country. Presidio Heights, Pacific Heights, Nob Hill, Russian Hill, Telegraph Hill, Marina, Cow Hollow and Sea Cliff. These neighborhood residents are a mixture of old established SF society, new technology stars, all areas of the Arts and a diversity of people, extraordinary architecture cultural activities and breathtaking views, that make San Francisco the "Sister City of Paris". Over the Golden Gate Bridge lies the prestigious Belvedere Island in Marin County. Now, it is up to your specific needs and wants to matching you up with any of these communities or others that lie further to the South and East of San Francisco. I would love to take you on a tour of these areas that I take great pride in calling home.

I would not disagree with what has been provided below. Assuming "San Francisco Bay Area" is defined by the 9 counties surrounding SF Bay, here are some examples of what you can find currently active in the $10-20M range:
If instant gratification is not a requirement, executing a custom build is always an option too (a plethora of hungry contractors await).
Are you looking for close in urban type location or you want several acres of privacy.
Please go to my blog to search for homes on the Peninsula.
