The highest bidders have shelled out more than $25 million combined. The proceeds of the auction this year will be donated once again to San Francisco based Glide, a charity that fights poverty and inequality. Glide also works with homelessness in the midst of a severe crisis of affordable housing in San Francisco. Glide was one of Buffett's late wife Susan's favorite charities.

The winning bidder and his or her friends will have lunch at one of Warren Buffett's favorite restaurants-the steakhouse Smith & Wollensky in New York City.
