Classicism meets art deco at the Imperial, which dates from 1931 and was designed by FB Blomfield, an associate of Lutyens. Rooms have high ceilings, flowing curtains, French linen and marble baths. There's the temple-like Thai restaurant Spice Route; the 1911 bar is highly recommended; and the cafe Atrium, Imperial serves the perfect high tea.
The hallways and atriums are lined with the hotel's venerable 18th- and 19th-century art collection.
