Crave a night of decadence? Skip the nightclub. Eat cake instead. Award-winning pastry chef Gale Gand at TRU in Chicago (312-202-0001) now offers her five-course dessert-tasting menu to the post-curtain crowd after 9 p.m. (sit at the bar to get it at any hour). Or have a Linzer torte and a glass of champagne at the new Viennese-style CAFÉ SABARSKY in New York (212-288-0665). The art nouveau cafe also serves Austrian dishes from chef Kurt Gutenbrunner of nearby Wallsé. —
