"Hotel Imperial Originally built as a residence for Prince Philip of Württemberg in 1863, this grand structure was opened as the Hotel Imperial in 1873. It indeed still resembles a palace, with Greek statues, chandeliers, and high, intricately designed stucco ceilings. The rooms bring imperial Vienna back to life, particularly in the suites. Visitors here feel like royalty, and sometimes they are. Guests have included a who’s who of celebrities and dignitaries, including Queen Elizabeth II, Indira Gandhi, and Michael Jackson. It's rumored that an apprentice chef at the hotel invented the well-known Imperial Torte in honor of Emperor Franz Josef I, a must-have for any sweet tooth. For some sweet sounds, be sure to check for Bösendorfer piano concerts in the 1873 HalleNSalon."
