Straight out of the golden age of 1930s Hollywood movies the Atlantic Bar is an Art Deco masterpiece, harking back to the days when staying in hotels was something to look forward to rather than a necessary 21st-century chore. Find immaculate barmen dressed as penguins, shuffling about the place and keeping the bar nibbles well stocked. Staggeringly expensive, you do at least get free cabaret if you choose the right time to pop in.
