Hidden at the heart of the Hilton Opera, Le Petit Bar has changed its name to “LPB”. 100 years after the start of prohibition, fans of cool new addresses and creative cocktails can now re-live this era which left its mark on the USA. The hotel has lavished attention on all the details : period furniture, subdued light, an appropriate playlist, not forgetting the barmen’s attire. Hilton Paris Opera, 108 rue Saint-Lazare, Paris 8 (01 40 08 44 44).
