Want your colleagues to really let loose? Then the Ivory Vaults is the place to go. Located within the vaulted cellars of Grade II-listed Ivory House, the 10,000sq ft venue is best known for its immersive medieval banquet evenings, where guests have the chance to interact with knights and wenches while dining on top-notch grub. The space can be hired for groups of 100-450, with nine separate areas able to hold 50 people each. There’ll be sword fights, dancing and plenty of merriment. Costumes can also be hired – even better for getting into the team spirit.
