Turns out that Jack Rose Dining Saloon has a basement, and now it’s finally putting it to use—for more drinking, of course.

The whiskey haven hasn’t finalized a permanent concept for the subterranean drinking den quite yet, but you can get a first glimpse of it during a Repeal Day party on Dec. 5. The $20 end-of-Prohibition celebration, from 10 p.m. to 1 a.m., will include burlesque performances and “prohibition-priced” glasses of punch for 50 cents.

Because a drinking holiday can’t be contained in 24 hours, Jack Rose has extended the festivities into “Repeal Week,” which goes from Nov. 28 through Dec. 4. During that time, it will serve some rare draft beers as well as a 1920s-inspired a la carte menu with dishes like steamed quail buns and lobster thermidor. On Repeal Day itself, there will also be a four-course tasting menu for $20 from 5 p.m. until the party starts at 10 p.m.
