One of the newer museums in New York City [1] is the Neue Galerie (1048 5th Ave., at 86th St., 212/628-6200, www.neuegalerie.org [2], 11 a.m.–6 p.m. Thurs.–Sun., adults $15, seniors and students $10, children under 12 not admitted), devoted solely to the fine and decorative arts of Germany and Austria from the first half of the 20th century.
Housed in a renovated Beaux-Arts mansion, the museum holds a large permanent collection of works by Gustav Klimt and Egon Schiele, a bookstore, design shop, and the smart Cafe Sabarsky, where you can indulge in Viennese coffee and a piece of Sacher torte.
