A restored masterpiece, the Elgin & Winter Garden Theatre is the world's last operating double-decker theater. Celebrating its centennial in 2013, the Winter Garden was built as the flagship for a vaudeville chain that never really took off, while the downstairs Elgin was converted into a movie house in the 1920s. Fascinating tours run Thursdays at 5pm and Saturdays at 11am.
Saved from demolition in 1981, the theaters received a $29 million facelift: bread dough was used to uncover original rose-garden frescoes, the Belgian company that made the original carpet was contacted for fresh rugs, and the floral Winter Garden ceiling was replaced, leaf by painstaking leaf.
