Pull out your pocketbooks, people. Your dream of dining alongside Berkshire Hathaway (NYSE:BRK.A) head Warren Buffett could finally become a reality. Watch Warren butter his roll. Watch him sip on a Coke (NYSE:KO). See him scarf down a tasty lunch at one of New York City's fabulous restaurants. And while you're at it, glean knowledge from his amazing brain about value investing and other titillating topics.

Via eBay (NASDAQ:EBAY), a lunch with Buffett is up for grabs. You can take along seven of your closest buds, too, should you pony up the winning bid. All proceeds will go to the Glide Foundation, a San Francisco-based charity, which provides all sorts of services to needy people. Another lunch with Buffett, this one in San Francisco, is being offered up at a live Thursday night auction in the city by the Bay.

The honor and pleasure of eating with the Oracle of Omaha won't come cheap, though. As of last check, the highest bid on eBay is up to $27,000. Whew! You best hurry, too. The auction closes tomorrow at midnight eastern time.

In the quirky world of eBay, though, there are usually substitutes, and this auction is no different. Instead of shelling out twenty large, you could instead have lunch with Warren Buffett's self-proclaimed "evil twin." That one's going for $7.50.

Or how about just having lunch with this person instead of Warren Buffett for $50? He/she is offering to meet anywhere, at any time, in Manhattan, and will donate proceeds to a New Jersey soup kitchen.

If you don't have an extra $30,000 sitting around for a lunch date, or the idea of paying to eat with two Buffett substitutes isn't your thing, then consider learning about deep value another way, with Tom Gardner's Motley Fool Hidden Gems newsletter.
