The rib-eye steak served at tonight’s state dinner for French President Francoise Hollande might not be the only thing that’s fat — the evening’s tab could be, too. CBS is reporting that the diplomacy and pageantry of state dinners — a longstanding tradition aimed at celebrating key international alliances — can cost more than half a million dollars apiece.

Here are the price tags for the first five such events of President Obama’s administration, per CBS, which got the figures through a Freedom of Information Act request (which the State Department took 13 months to RSVP to). No word on why the dinners for Germany’s Angela Merkel and South Korea’s Lee Myung-bak cost so much less than the others.
