Select your visit duration... pick a date and time.... then go through checkout as usual. There is no payment required but we will need your address. Each table has its own ‘duration time’ so if the one you want is not available try a different duration.
Please note 'Quantity' on the check-out page should be left at 1 if booked on a desktop or tablet (this option isn't obvious on a phone though). This is not the number of guests at your table!
