Oklahoma City's grand downtown hotel, opened in 1911 by oil baron William Balser Skirvin and now operating as a Hilton after a long, expensive 2007 restoration. The thirteen-storey beaux-arts building has hosted seven presidents, and the interiors — gilded ceilings, marble corridors, the Art Deco-era ballroom and an underground swimming pool — have all been faithfully brought back.
The Park Avenue Grill on the ground floor is decent, the lobby bar is busier than you would expect on a weekday evening, and the building itself is worth a walk-through even if you aren't staying. The hotel's reputation as one of the most haunted in America does, fairly or otherwise, contribute to its mystique.
