The Grenadier built in 1720 as the officers mess for senior infantry regiment of the British army, located in the courtyard of the Foot Guards barracks. It was opened to the public as a tavern in 1818 named the Guardsman, but then renamed the Grenadier in honour of the Grenadier Guards at the battle of Waterloo. You would have real problems finding this pub as it is hidden away in a small mews near Hyde Park Corner. Notable people who have used this inn, include The Duke of Wellington, king George IV, Madonna and Prince William. There are thousands of monetary notes stuck to the ceilings, these have been placed by customers to appease the ghost of Cedric, Legend has it that Grenadier is named after young Cedric, a soldier who was caught cheating at cards and punished by being beaten to death. No one knows exactly when this ghastly deed occurred, but it is thought to have been in September as that is when ghostly happenings are rife. Visitors hang money from the ceiling in an attempt to pay his debt, but poor Cedric seems to remain trapped on earth.
