Birthday packages are available during our usual opening hours, with the last bookable slot at 16:00.

The time you choose when you book your birthday package is for entry to the experience. We’ll reserve a table for you in The Guildhall Café from 30 minutes after you enter the experience and that’s yours for three hours. For example, if your booking is for 10:00, your table will be reserved from 10:30 and you will have this table until 13:00.

No decorations, such as balloons or confetti etc, are allowed (but don’t worry – we’ll make a special fuss of the birthday person)
