You can manage your booking via the online guest portal accessed from the link in your booking confirmation email or from the 'place your order' button in the preorder email.
Add your guests' names to the booking.
If you wish you can also add their email address to send them a link to the portal so that they can enter their own menu choices. Alternatively, you can order for everyone by simply adding the menu choices for each guest. Make sure you click 'complete order' for each guest to finalise their choices. You'll notice the knife and fork icon change colour when the order has been completed.
