Mayor Rahm Emanuel will be hosting the late-night post-inagural party on Jan. 21 in one of Washington's newest venues, the Hamilton, just down the block from the White House. How late? Runs from 11 p.m. to 3 a.m. in an event billed as a "Chicago-Style after hours."

The invite is from Emanuel and the Presidential Inaugural Committee co-chairs, Matthew Barzun, Eva Longoria, Jane Stetson, Frank White, Stephanie Cutter, Jen O'Malley Dixon, Patrick Gaspard, Rufus Gifford, Jim Messina and Julianna Smoot.

Emanuel's late-night party at the Democratic National Convention in Charlotte, N.C. was a sought-after ticket and jammed.
