It now focuses on first-hand titles (especially travel-related material). The Marylebone branch is now the flagship store, housed in a former Edwardian bookshop with long oak galleries, graceful skylights and William Morris prints. It is alleged to be the first custom-built bookshop in the world.

Ginger Pig

Originating on the edge of the moors in North Yorkshire, Ginger Pig was founded by Tim Wilson having farmed his pasture, producing cattle, sheep and pigs, with a passion for sustaining rare breeds. Tim has built a network of like-minded farmers to help supply its butchers’ shops with the best produce in the country. At the heart of everything they do is good animal husbandry and welfare; livestock that is looked after well in the field simply tastes better on the plate. All their beef dry-age all of our beef in-house to a minimum of 28 days and don't miss out on their lunch time takeaway roast's if you work near by!
