Paul Ryan to headline ‘Mad Men' themed dinner

— -- Wisconsin Republican and possible VP pick Paul Ryan will headline a "Mad Men"-themed gala dinner in Washington, D.C., Tuesday hosted by the Competitive Enterprise Institute, a free-market think tank.

The annual dinner, held at the Hyatt Regency Washington on Capitol Hill, is sold out, organizers said. Attendance at the event costs  $5,000-$40,000 per table or $250 for an individual seat.

Ryan is scheduled to speak at the gala after hosting a roundtable discussion on behalf of Romney's presidential campaign in Raleigh, N.C., earlier that day.

An after-party will follow the dinner, where the Old Fashioned is sure to be the drink of choice.
