As summer comes around, a secret outdoor restaurant and bar pops up at the back of St Pancras International Hotel. Booking Office 1869’s terrace offers a backdrop of Victorian architecture and the chance to get fizzy while topping up the vitamin D thanks to a partnership with Laurent-Perrier Champagne. Pair bubbles with fresh oysters, feast on small bites or go big by devouring one of the restaurant’s signature burgers, hearty sarnies or crunchy, refreshing salads.
