Abraham Lincoln's purported playbill for his fateful night at Ford's Theatre kicked off the considerable collection of Lincoln memorabilia at this circa-1885 steakhouse, which is anything but a museum. Keens keeps things fun, with activities such as bar trivia (example: In The Prisoner of Second Avenue, which young actor did Jack Lemmon "mug?"). Answer three correctly and you get a free cigar. No matter how successful your guesses, the bar is wonderful, manned by convivial barkeeps who know how to make a drink and can offer suggestions on the more than 200 scotches on hand. It's also the place for a pub menu of fresh oysters, turkey schnitzel and prime rib rash. For a more formal dining experience there are a number of prime dry-aged steak cuts, roasted buttermilk chicken and Dover sole. Without going into detail, everything's good.
