(CBS) – It’s playoffs time, and that means another friendly wager between two mayors with teams looking to advance.

On Friday, Chicago Mayor Rahm Emanuel said he has made a bet with San Francisco Mayor Ed Lee on the best-of-five National League Division Series between the Cubs and Giants, which starts Friday night at Wrigley Field.

If the Cubs take a dive, Emanuel will fork over a variety of locally produced, small-batch liquor, such as bourbon from KOVAL Distillery and a growler of Bad Intentions beer from Vice District Brewing; food delicacies such as Robinson’s ribs, steaks from Harry Caray’s Italian Steakhouse, “soulful side dishes” from MacArthur’s Restaurant and Eli’s Cheesecake.

Emanuel will also make a contribution to the charity of Lee’s choice if the Cubs don’t prevail.

“The Cubs are the best team in baseball, and I fully expect Chicago to Fly the W,” Emanuel said, referring to the flags of victory flown at and around Wrigley Field.

If San Francisco goes down in flames, Lee is on the hook for high-end booze from his city. He has also promised to make a donation to Becoming A Man, or BAM, the youth mentoring program championed by Emanuel.
